Rare imaging appearance of adenoid cystic carcinoma of the breast: A case report.

ABSTRACT: Adenoid cystic carcinoma (ACC) of the breast is a rare tumor comprising <0.1% of all breast malignancies. The present study reports the case of a 66-year-old woman who underwent multiple imaging techniques, including mammography, ultrasonography and magnetic resonance imaging (MRI). The patient reported gradual enlargement of a mass in the left breast. Mammography identified a high-density, irregular mass, with nipple retraction. Ultrasonography revealed an irregular, complex cystic and solid mass with an unclear margin in the subareolar region. The internal vascularity was seen on Doppler examination. The lesion on MRI was also mixed cystic and solid, with an irregular shape and irregular margins. The solid part of the lesion appeared heterogeneously isointense on T1-weighted imaging (WI) and a slightly high signal on T2WI, and exhibited internal septations with a low signal on T2WI. Following injection of contrast agent, the enhancement of the solid part was rapid and heterogeneous. The cystic parts of lesion appeared as high-signal on T1WI and T2WI. The tumor infiltrated the left nipple and adjacent skin. The patient underwent a left modified radical mastectomy with axillary lymph node dissection. The pathological examination confirmed the tumor as ACC of the left breast. The axillary lymph nodes were negative for tumor metastasis. Therefore, the differential diagnosis of mixed cystic and solid breast masses with unclear margins and internal septations on T2WI exhibiting delayed enhancement, must include ACC.

Cutaneous adenoid cystic carcinoma of lower eyelid: Case report of a rare malignant entity.

Project description:Introductioncutaneous adenoid cystic carcinoma is a rare epithelial tumor with slow development, it is most often described in the scalp; palpebral involvement is very rare. And is accompanied by local aggressiveness and frequent recurrence. The aim of this work is to discuss the management and the interest of a close surveillance of adenoid cystic carcinoma.Case presentationThe authors report a case of palpebral cystic adenoid carcinoma in a 65-year-old patient who underwent surgical excision followed by reconstruction of the loss of substance.DiscussionCutaneous cystic adenoid carcinoma of the eyelids remains a very rare entity that must be evoked in front of a nodular cutaneous palpebral tumor that progresses slowly. An early diagnosis and a complete excision guarantee a better prognosis.ConclusionAdenoid cystic carcinoma, because of its local aggressiveness and its capacity to recur despite satisfactory surgical removal, requires long-term surveillance. Its surgery may be responsible for functional and aesthetic sequelae.

Adenoid cystic carcinoma of the breast - Discordant size on imaging and pathology: A case report and review of literature.

Project description:IntroductionAdenoid cystic carcinoma (ACC) is an uncommon tumour of the breast. It is known for its rare lymph node involvement and distant metastasis. A triple-negative breast cancer that has a favorable prognosis compared to other triple negative ductal carcinomas, it accounts for approximately 0.1-1% of all breast cancers.Presentation of caseWe report a case of a 69-year-old female with a palpable left breast mass who underwent multiple imaging modalities with significant size variance between the studies. Breast conserving therapy (BCT) was performed with axillary sentinel lymph node biopsy (SLNB) followed by radiation therapy (RT). Pathological examination confirmed the tumour as ACC.DiscussionACC, known as an persistent if low-grade malignant tumour of salivary gland, is considered to have low-malignant potential in the breast. It is a very rare subtype and from this scant data, there is minimal mention about size discrepancy between imaging modalities such as ultrasound and MRI.No consistent MRI features have been demonstrated, with the exception of T2 hyperintensity in larger lesions and T2 iso-intensity in smaller lesions. Ultrasound demonstrates primarily a hypoechoic or heterogenous mass with minimum vascularity, consistent with our radiographic findings.ConclusionACC is a rare entity in breast cancer pathology. Its size can be highly variable as measured by various radiographic modalities, and final Pathology from the surgical specimen is, as always, required for an accurate tumoral diameter. With that caveat, careful utilization of pre-operative imaging modalities is critical in pre-surgical planning to choose the appropriate surgery.

Adenoid cystic carcinoma mimicking an oroantral fistula: a case report.

Project description:Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site.

Male Adenoid Cystic Carcinoma of the Breast.

Project description:Adenoid cystic carcinoma (ACC) of the breast, a rare malignancy that makes up less than 0.1% of all breast malignancies, is much rarer in males than in females. Due to the rarity of this disease, an optimal treatment strategy for male breast ACC has not been established, and therapy for male patients is currently based on guidelines for female patients. According to previous reported cases, some authors believe that male breast ACC may have higher invasive potential than female breast ACC and the prognoses in male patients may be worse than those in female patients. Therefore, a more proactive diagnosis and treatment regimen may be required. However, the clinical feature of our case is inconsistent with this view. Herein we report the case of a 24-year-old male without any antecedent medical or family history who presented with a slow-growing lump on his left chest wall for 5 years. The patient initially underwent lumpectomy, and the mass was pathologically diagnosed as breast ACC. Systemic examination was performed, and no evidence of distant metastasis was found. Then, he received modified radical mastectomy and ipsilateral axillary lymph node dissection. The mastectomy pathological examination revealed that no cancerous tissue was detected around the primary tumor bed, and all 22 axillary lymph nodes were negative. The patient did not receive postoperative chemotherapy, radiotherapy or endocrine therapy and remained well after 28 months of follow-up. In this study, we review the literature and summarize the clinical manifestations, imaging and histopathological characteristics, treatments and outcomes of male breast ACC. We share our experience in the hopes that this evidence will aid in the development of better therapeutics.

An unusual case report of pulmonary adenoid cystic carcinoma metastasis to the kidney. Case report and literature review.

Project description:Adenoid cystic carcinoma (ACC) is a malignant neoplasm, frequently affecting the salivary glands, and rarely occurring in other locations. ACC is characterized by slow growth, perineural invasion, local and late recurrence after original treatment. However, renal metastasis of ACC is very rare. To our best knowledge, only 11 cases of ACC metastasis to the kidney have been reported in the English literature to date. Herein, we presented a rare case of a 70-year-old man with renal metastasis from ACC of the right lung after 3 years of primary presentation. Our patient underwent right radical nephrectomy and histologically confirmed as Metastatic Adenoid Cystic Carcinoma.

Multi-Omics Characterization and Origin Assessment of Bilateral Lung Adenoid Cystic Carcinoma: A Case Report.

Project description:BackgroundPrimary adenoid cystic carcinoma (ACC) of the lung, which arises from the bronchial gland and is rare, accounting for only 0.04-0.2% of all primary lung tumors. The genetic profiling of bilateral ACC of unknown primary site and application in postoperative decision-making are less reported.Case presentationA 57-year-old male with a smoking history of over 30 years and multiple nodules in both lungs was present to our department. After assessing the bilateral solid nodules in his Positron Emission Tomography-Computed Tomography (PET/CT) scan, malignant lesions at the left lower lung, right lower lung, and right middle lung are suspected. Sequential selective video-assisted thoracoscopic surgeries (VATS) were performed. A genetic alteration test of 425 cancer-related genes and global gene expression profile of the specimens revealed intrapulmonary metastasis existed. The patient was followed up for three years without recurrence and tissue mutations in liquid biopsy.ConclusionWe present a way of omics-based multiple pulmonary lesions origin assessment, facilitating post-operative differential diagnosis and treatment decision for difficult cases.

Genomic landscape of adenoid cystic carcinoma of the breast.

Project description:Adenoid cystic carcinoma (AdCC) is a rare type of triple-negative breast cancer (TNBC) characterized by the presence of the MYB-NFIB fusion gene. The molecular underpinning of breast AdCCs other than the MYB-NFIB fusion gene remains largely unexplored. Here we sought to define the repertoire of somatic genetic alterations of breast AdCCs. We performed whole-exome sequencing, followed by orthogonal validation, of 12 breast AdCCs to determine the landscape of somatic mutations and gene copy number alterations. Fluorescence in situ hybridization and reverse-transcription PCR were used to define the presence of MYB gene rearrangements and MYB-NFIB chimeric transcripts. Unlike common forms of TNBC, we found that AdCCs have a low mutation rate (0.27 non-silent mutations/Mb), lack mutations in TP53 and PIK3CA and display a heterogeneous constellation of known cancer genes affected by somatic mutations, including MYB, BRAF, FBXW7, SMARCA5, SF3B1 and FGFR2. MYB and TLN2 were affected by somatic mutations in two cases each. Akin to salivary gland AdCCs, breast AdCCs were found to harbour mutations targeting chromatin remodelling, cell adhesion, RNA biology, ubiquitination and canonical signalling pathway genes. We observed that, although breast AdCCs had rather simple genomes, they likely display intra-tumour genetic heterogeneity at diagnosis. Taken together, these findings demonstrate that the mutational burden and mutational repertoire of breast AdCCs are more similar to those of salivary gland AdCCs than to those of other types of TNBCs, emphasizing the importance of histological subtyping of TNBCs. Furthermore, our data provide direct evidence that AdCCs harbour a distinctive mutational landscape and genomic structure, irrespective of the disease site of origin.

Neoadjuvant chemotherapy followed by radical vulvectomy for adenoid cystic carcinoma of Bartholin's gland: a case report.

Project description:BackgroundAdenoid cystic carcinoma (ACC) of the Bartholin's gland is a rare cancer of the female genital tract for which there is no consensus on treatment. As there are no current reports on neoadjuvant chemotherapy followed by surgery for this disease, our case explores the effectiveness of neoadjuvant chemotherapy.Case descriptionWe report a case of ACC of Bartholin's gland. The patient is a 69-year-old woman with a left vulvar mass. Pelvic magnetic resonance imaging (MRI) showed a left perineal occupying lesion with indistinct boundaries to the surrounding tissues. The patient received two cycles of neoadjuvant chemotherapy with a regimen of paclitaxel combined with cisplatin and the mass was significantly reduced. Subsequently, she received a radical vulvectomy and left inguinal lymph node dissection. The operation was successful, and the patient was treated with simultaneous radiotherapy and chemotherapy after the surgery. The patient is currently 14 months postoperative and reports no significant pain with normal urination and defecation. The pelvic MRI was reviewed regularly, and there was no sign of recurrence.ConclusionsAfter neoadjuvant chemotherapy, the extent of the lesion was significantly reduced, which reduced the difficulty of surgery, thus reducing surgical complications and enabling complete resection of the tumor tissue. Based on the treatment of this patient, we speculate that preoperative neoadjuvant chemotherapy may be a better choice for patients with extensive and fixed lesions.

Treatment of adenoid cystic carcinoma of the mobile tongue with anterolateral thigh flap reconstruction: A case report.

Project description:RationaleAdenoid cystic carcinoma (ACC) is an infrequent malignant neoplasm of the salivary glands. The clinical and pathological characteristics include slow growth, perineural invasion, and local recurrence. ACC of the mobile tongue is rarely reported in the literature.Patient concernsWe describe a case of a 43-year-old man patient with numbness and growth in the tongue for 1 month duration. The patient reported a long-term smoking and drinking habit.DiagnosesA biopsy was carried out and histopathological analysis confirmed as diagnosis of adenoid cystic carcinoma. Computed tomography (CT) of the head and neck enhanced scanning revealed an ill-defined high density mass with altered enhanced signal entities involving the anterior 2/3rd of the tongue.InterventionsThe patient was treated with surgery and adjuvant radiotherapy. Incision was placed over the anteriorly till 2/3rd of tongue and then the femoral anterolateral free flap was used to repair and reconstruct the defect of tongue.OutcomeThe patient is currently under a postsurgical 29-month regular follow-up, showing good swallowing and speaking function without any recurrence and metastasis.LessonsThis case report suggests that surgery and adjuvant radiotherapy are suitable procedures for patients with resectable ACC of the mobile tongue.

Multiple chromoanasynthesis in a rare case of sporadic renal leiomyosarcoma: case report

Project description:Renal leiomyosarcomas (LMS) are extremely rare neoplasms with aggressive behaviour and poor survival prognosis. The most frequent somatic events in leiomyosarcomas are mutations in TP53, RB1, ATRX and PTEN genes, chromosomal instability and chromoanagenesis. By using chromosomal microarray analysis we identified monosomy of chromosomes 3 and 11, gain of Xp (ATRX) arm and three chromoanasynthesis regions (6q21-q27, 7p22.3-p12.1 and 12q13.11-q21.2), with MDM2 and CDK4 oncogenes copy number gains, whereas no CNVs or tumor specific SNVs in TP53, RB1 and PTEN genes were observed.
