Orbital myiasis on recurrent undifferentiated carcinoma in the COVID-19 era: a case report and brief review of the literature

ABSTRACT:

Background

Myiasis is defined as the infestation of living tissues by Diptera larvae. Ophthalmic involvement occurs in less than 5% of cases. As the most uncommon type of involvement, orbital myiasis usually affects patients with poor personal hygiene, a low socioeconomic status, a history of surgery, and cancer.

Findings

In January 2020, an 89-year-old man presented to the Oculoplastic Department of Farabi Eye Hospital (Iran) with a history of left-side progressive orbital mass for six months. A large infiltrative mass of the left orbit with extension to the globe, periorbita, and adnexa was remarkable at the presentation, and its appearance suggested malignancy. Our findings persuaded us to perform exenteration and histopathological evaluation which were reported as “undifferentiated carcinoma”. Regular follow-up visits were recommended. In June 2020, with a 3-month delay, the patient presented with the recurrence of the mass complicated with mobile alive larva. Examinations revealed numerous maggots crawling out of an ulcerative and foul-smelling lesion. He stated that fear of COVID-19 infection postponed his follow-up visit. The patient underwent immediate mechanical removal of larvae, followed by wide local excision of the mass.

Conclusion

Patients with carcinoma of the adnexal tissues seem to be more prone to myiasis infestation even though it is an uncommon disease. Since COVID-19 is an ongoing pandemic with no end in sight appropriate protocols should be implemented to prevent loss of follow-up in these high risk patients.

Lemierre's syndrome: Case report and brief literature review.

Project description:Lemierre's syndrome has been shown to be increasing in incidence in the past 20 years with one popular suggesting that said rise occurred from less aggressive antibacterial coverage. We report a case of Lemierre's syndrome and also reviewed the 15 most recent case reports. A previously healthy 25 year old male who initially developed sore throat and flu-like symptoms, was prescribed antibacterials as an outpatient but was hospitalized for worsening symptoms. He was later diagnosed with Lemierre's syndrome and improved clinically with IV antimicrobials alone. From our concise literature review, we determined that a decrease in antibiotic prescriptions may not fully explain why the incidence of Lemierre's has been increasing. Thus, future research should be focused in evaluating possible worsening susceptibilities to antibiotics and improvements on detection. We also advise physicians to be aware of the signs and symptoms of this rare but potentially fatal condition as well as the available detection methods and treatment.

Mixed acinar-endocrine carcinoma of pancreas: A case report and brief review of the literature.

Project description:Mixed acinar-endocrine carcinoma (MAEC) of the pancreas is a rare entity. We present a 65-year-old Chinese female who was admitted with jaundice and nagging epigastric pain with intermittent diarrhea for 1 month. She eventually underwent abdominal magnetic resonance imaging, which showed an 8×6 cm mass in the head of the pancreas and showed two abnormal lesions in the liver simultaneously. MAEC of the pancreas with synchronous hepatic metastasis was confirmed with immunohistochemistry after Whipple operation and hepatic partial resection of the lesions. Postoperative recovery of this patient was uneventful, and no evidence of recurrence or metastasis was observed after 12 months of follow-up. MAEC of pancreas is thought to be extremely rare and lack of typical clinical symptoms. The prognosis is poor overall, but early detection with complete resection may be beneficial to patients.

Deep penetrating nevus: a case report and brief literature review.

Project description:BackgroundDeep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic nevus. It often goes unrecognized due to its relative rarity.Case presentationHere we report a case of DPN of the left anterior leg in a 51-year old female. A brief review of the literature shows that these lesions have a distinct growth pattern and cellular morphology that can differentiate these lesions from other entities including malignant melanoma.ConclusionIt is important to recognize these features because DPN carries a better prognosis than malignant melanoma.

Recurrent bladder urothelial carcinoma complicated with primary bladder large cell neuroendocrine carcinoma: a case report and literature review.

Project description:ObjectiveTo improve the understanding, diagnosis and treatment of bladder large cell neuroendocrine carcinoma (LCNEC).MethodsA clinical case of bladder LCNEC admitted to our hospital was reported. The epidemiology, prognosis, diagnosis and treatment methods of large cell neuroendocrine carcinoma were reviewed. The diagnosis and treatment status and prognosis were discussed based on the literature.ResultsThe female patient was admitted to hospital for "more than 4 years after TURBT and intermittent hematuria for more than 2 years". She was diagnosed as recurrent bladder cancer and underwent "radical cystotomy + hysterectomy". The postoperative pathological findings were high-grade urothelial carcinoma of the bladder neck and large cell neuroendocrine carcinoma of the bladder. The patient recovered well after surgery, but refused radiotherapy and chemotherapy and is still under close follow-up.ConclusionBladder LCNEC is clinically rare, has unique pathological features, is more aggressive than traditional urothelial carcinoma, and has a poor prognosis. Surgery, chemotherapy and radiotherapy should be combined with multi-mode treatment.

Targeted-gene sequencing of an undifferentiated gallbladder carcinoma: a case report.

Project description:BackgroundUndifferentiated carcinomas of the gallbladder are extremely rare. Most undifferentiated carcinomas are accompanied by adjacent foci of other conventional carcinomas, and a transition zone is shared between them. However, genetic alterations of undifferentiated gallbladder carcinoma and the similarities or differences between the undifferentiated carcinoma and the foci conventional carcinoma are unknown.Case presentationHerein, we report a case of undifferentiated gallbladder carcinoma with osteoclast-like giant cells with invasion into the liver, duodenum, and stomach in a 56-year-old man. The tumor was microscopically formed from the tubular adenocarcinoma (< 5% of the entire tumor), the undifferentiated carcinoma, and a transition zone between them. Four somatic mutations (TP53, TERT, ARID2, and CDH1), three amplifications (CCND1, FGF19, and MET), and a tumor mutation burden (TMB) of 3.45 muts/Mb were detected in the undifferentiated component using targeted gene sequencing, whereas 102 somatic mutations (including TP53, TERT, ARID2, and CDH1), one amplification (CCND1), and a higher TMB of 87.07 muts/Mb were detected in the tubular component. This patient died of tumor recurrence 2 months after the surgery.ConclusionsThe undifferentiated gallbladder carcinoma had its unique molecular alterations. The similarities in the genetic alterations of the undifferentiated carcinoma and adenocarcinoma provide evidence of a common origin at the genetic level. The occurrence of an undifferentiated carcinoma may be due to heterogeneity-associated branched evolution from the tubular adenocarcinoma.

Imaging performance of thoracic SMARCA4-deficient undifferentiated tumor: a case report and literature review.

Project description:BackgroundSMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a class of high-grade malignant tumors that has only been described in recent years, with an undifferentiated or rhabdoid morphology and genetic deletion of SMARCA4 (BRG1), a subunit of the BRG1-associated factors (BAFs) chromatin remodeling complex. It is a rare tumor type that occurs in young to middle-aged men and usually presents as a compressive thoracic mass with rapid progression and poor prognosis. However, much remains unknown about the clinical and imaging manifestations of the disease.Case descriptionHerein, we report a 51-year-old man who came to our hospital with multiple enlarged lymph nodes in the chest after a computed tomography (CT) examination at another hospital. The patient underwent conventional ultrasound (US), contrast-enhanced ultrasound (CEUS), magnetic resonance imaging (MRI), 18F-fluorodeoxyglucose positron emission tomography/CT (PET/CT), and finally confirmed the diagnosis of SMARCA4-UT by US-guided puncture biopsy. After symptomatic management, the patient was transferred to another hospital and we performed a short-term follow-up.ConclusionsDuring this procedure, we obtained a series of relevant clinical and imaging data, especially US and CEUS images, which were described for the first time, offering valuable imaging information that will contribute to the clinical diagnosis of this disease to a certain extent. Moreover, this case highlights the efficacy of CEUS in identifying internal necrosis within tumors and lymph nodes, thereby improving the success rate of obtaining tumor tissue for pathological diagnosis. These findings substantiate the practical utility of US and CEUS in the context of mediastinal SMARCA4-UT, emphasizing their potential for widespread clinical adoption.

Recurrent intrathoracic dedifferentiated liposarcoma: A case report and literature review.

Project description:BackgroundLiposarcoma (LPS) is the second most common type of soft tissue sarcoma, accounting for approximately 15-20% of all the sarcomas. Primary intrathoracic LPS, however, is quite rare. LPS is a malignant mesenchymal tumor, comprised of lipogenic tissue with varying degrees of atypia. It can be subclassified into well-differentiated LPS (WDLPS), myxoid LPS (MLPS)/round cell LPS, pleomorphic LPS (PLPs), and dedifferentiated LPS (DDLPS), based on the histology.Case presentationA 76-year-old male patient initially presented to the emergency room with a complaint of precordial chest pain for one month. Computed tomography (CT) of his chest showed a large, 8 cm × 8 cm x 10 cm, supradiaphragmatic, complex solid mass in the lower left hemithorax, along the anterior chest wall. Chest wall mass excision revealed dedifferentiated LPS, with excision of margins. Positron emission tomography (PET) scan did not show metastatic disease. Seven months later, he presented with shortness of breath, and CT of the chest showed large, left pleural-based masses, causing compression of surrounding structures. He was not a candidate for surgical resection. This patient subsequently failed chemotherapy and opted for hospice.ConclusionIntrathoracic LPS is a rare tumor. Recurrence is higher with dedifferentiated histology forms. Radical surgery with excision of margins is the primary recommended treatment.

Case Report: SMARCA4 (BRG1)-deficient undifferentiated carcinoma of gallbladder with genetic analysis.

Project description:SMARCA4 (BRG1)-deficient undifferentiated carcinoma is a rare and highly aggressive malignancy. It has been reported to occur in a multiple range of organs. However, to the best of our knowledge, SMARCA4 (BRG1)-deficient undifferentiated carcinoma of gallbladder has not yet been reported. Here, we describe a case of SMARCA4 (BRG1)-deficient undifferentiated carcinoma of gallbladder. Through comprehensive genetic analysis, we hypothesized that in addition to SMARCA4 (BRG1) deficiency, other genetic changes might also be involved in the tumorigenesis of undifferentiated gallbladder cancer in this patient, particularly somatic mutations in the CTNNB1, KRAS, PIK3CA, TP53, CREBBP, and FANCI genes. To the best of our knowledge, this is the first report of SMARCA4 (BRG1)-deficient undifferentiated carcinoma of gallbladder with genetic analysis.

Immunotherapy Combined With Chemotherapy for Postoperative Recurrent Penile Squamous Cell Carcinoma: A Case Report and Literature Review.

Project description:Penile squamous cell carcinoma (SCC) is a rare malignant tumor in males with a poor prognosis. Currently, the primary treatment is surgery. Recurrent cases have limited treatment options after failed radiotherapy and chemotherapy. The therapeutic effect of immunotherapy in penile SCCs has not been reported. Tislelizumab, a new PD1 inhibitor, has shown a satisfactory impact in treating head and neck SCC and lung SCC combined with chemotherapy. However, there is currently no report on its efficacy in penile SCC. Here, a 76-year-old man with multiple enlarged inguinal lymph nodes 11 months after radical surgery for penile SCC was administered immunotherapy (tislelizumab) combined with chemotherapy (albumin paclitaxel plus nedaplatin) for 2 cycles. Pelvic Magnetic resonance imaging (MRI) showed that the multiple lymph nodes in the groin area disappeared. To our knowledge, this is the first case report of immunotherapy combined with chemotherapy showing promising results in recurrent penile SCC. It provides a basis for developing a new treatment option combining immunotherapy and chemotherapy, whose efficacy needs to be further evaluated in penile SCC.
