Project description:Concurrence of renal cell carcinoma (RCC) and urothelial carcinoma (UC) in the same kidney is a rare phenomenon. It is critical to define this unusual disease to avoid a delay in diagnosis and improve the prognosis. The present study describes a case of a 71-year-old patient with synchronous ipsilateral RCC and UC of the renal pelvis and ureter. The patient presented with intermittent attacks of left loin pain with frank hematuria for 3 months and a weight loss of 5 kg over the same period of time. The patient had been a chronic heavy smoker for >45 years. Physical examination revealed stable vital signs; however, a mobile, non-tender mass was palpated in the left upper abdomen. A left nephroureterectomy with the removal of a bladder cuff was performed. Histopathological examination revealed a papillary RCC with a pathological stage of pT1N0Mx and a high-grade UC of the renal pelvis and ureter with a pathological stage of pT3-pN1-pMx. The postoperative recovery was good, and the patient was referred to an oncology center for further management. Previous reports have failed to identify definitive risk factors for the concurrence of RCC and UC. However, 24% of the patients in the various case reports in the literature were smokers. The most common presenting complaints included weight loss and painless hematuria. The concurrence of RCC and UC in the same kidney is a rare entity, and it frequently leads to a worse prognosis than the occurrence of RCC alone. Radical nephroureterectomy is the main line of treatment for patients with upper tract UC.

Project description:BACKGROUND:Multiple primary malignant neoplasms are not frequent but are increasing in incidence. Some of them are associated with genetic syndromes such as von Hippel-Lindau syndrome and Li-Fraumeni syndrome. Dedifferentiated liposarcoma is one of the rarest soft tissue tumors, and clear cell renal carcinoma is the most frequent kidney cancer. The concomitant presence of these tumors is extremely rare; however, some cases have been reported, none of them presenting with liposarcoma of the limbs. We report an interesting case of a patient with synchronous multiple primary tumors presenting with a very rare liposarcoma associated with renal cell carcinoma (a very rare association). A review of the literature and a collection of similar cases published previously are also provided. CASE PRESENTATION:We report a case of a 62-year-old Hispanic man who presented to our institution with a left thigh mass compatible with dedifferentiated liposarcoma synchronous with metastatic clear cell renal carcinoma. Multiple treatment lines were provided with no response, with a further metastatic transformation. Genetic analysis by liquid biopsy showed some mutations that were not susceptible to targeted therapy. At the time of this report, the patient is undergoing palliative care because his nonresponsive metastatic disease persists. CONCLUSIONS:We present the first reported case of clear cell renal carcinoma synchronous with dedifferentiated liposarcoma of a limb. The association between renal cell carcinoma and dedifferentiated liposarcoma is unusual, and there are few reports of this presentation in the literature. More research about these tumors along with genetic tests needs to be performed to seek a better understanding of the fundamental basis of this rare association.

Project description:IntroductionEven though colorectal cancer is one of the most frequent in the world, its simultaneous presence with other neoplasms, such as renal, is still rare in incidence. This article aims to report and expose a literature review of the synchrony of colorectal cancer and renal carcinoma.Presentation of caseA 57-year-old female patient complaining of diffuse abdominal pain that worsened with food and improved with evacuation, especially in the periumbilical region and right iliac fossa, from moderate to strong intensity, starting 1 year ago, worsening in the last 3 months. An abdominal CT scan was performed, showing a lesion in the right kidney and a narrowing of the ascending colon lumen. Due to the possibility of cure, we opted for right colectomy and right nephrectomy at the same surgery.DiscussionSynchronous tumors are neoplasms in which the diagnostic interval is up to 6 months, and must be differentiated from metachronic neoplasms and even metastases between tumors. The incidence of synchronous colorectal and renal cancer is rare but appears to be divergent.ConclusionThe presence of synchronous tumors can be evidenced in imaging tests, such as CT scan, but appropriate diagnostic tests for each neoplasm, such as colonoscopy, should not be ruled out. The treatment of choice must be surgery, when possible, with the options of conventional access, videolaparoscopic and robotic surgery.

Project description:Lipomas of the cerebellopontine angle (CPA) and internal auditory canal (IAC) are relatively rare tumors. Acoustic neurinoma is the most common tumor in this location, which often causes hearing loss, vertigo, and tinnitus. Occasionally, this tumor compresses the brainstem, prompting surgical resection. Lipomas in this area may cause symptoms similar to neurinoma. However, they are not considered for surgical treatment because their removal may result in several additional deficits. Conservative therapy and repeated magnetic resonance imaging examinations for CPA/IAC lipomas are standard measures for preserving cranial nerve function. Herein, we report a case of acoustic neurinoma and CPA lipoma occurring in close proximity to each other ipsilaterally. The main symptom was hearing loss without facial nerve paralysis. Therefore, facial nerve injury had to be avoided. Considering the anatomical relationships among the tumors, cranial nerves, and CPA/IAC lipoma, we performed total surgical removal of the acoustic neurinoma. We intentionally left the lipoma untreated, which enabled facial nerve preservation. This report may be a useful reference for the differential diagnosis of similar cases in the future.

Project description:Multiple primary malignant neoplasms (MPMNs) are defined as the presence of two or more malignancies with different histologies in the same patient. MPMNs are rare, accounting for fewer than 4% of all tumor cases. Depending on the time interval between the diagnosis of the different malignancies, they are classified as either simultaneous or metachronous MPMNs, with simultaneous being rarer in MPMNs. Here, we present a 63-year-old female patient presenting with multiple primary renal and thyroid carcinomas and discuss the risk factors, treatment options, and prognosis of rare dual carcinomas. We focus on managing multidisciplinary teams and selecting individualized treatment options to deliver valuable treatment strategies to patients.

Project description:Primary peritoneal malignant tumors are exceptional. Among them, clear cell carcinoma is extremely rare, being only thirteen cases previously reported in the literature since 1990. We report a case of a 48-year-old Caucasian woman who was treated at the University General Hospital of Alicante. She consulted because of progressive abdominal pain over the last seven months, with the initial diagnosis of renal-ureteral colic. Ultrasound and computed tomography of the abdomen and pelvis revealed a 25 × 15 cm, well-defined cystic lesion with papillary projections, centrally located in the abdomen. The radiology report suggested a primary ovarian tumor versus peritoneal implant as the first option. The patient underwent an exploratory laparotomy showing a large cystic mass located in the urinary bladder peritoneum, firmly attached to the mesentery. The entire abdominal tumor was completely excised, and total hysterectomy with bilateral salpingo-oophorectomy and infra-colical omentectomy were performed. The final histological study revealed a new case of primary peritoneal clear cell carcinoma located in the urinary bladder peritoneum, firmly attached to the mesentery. Grossly, it was well-circumscribed and multicystic with papillary growth involving part of the inner wall. Microscopically, it showed tubulocystic and papillary patterns with highly atypical tumor cells. After an extensive immunohistochemical analysis, the most relevant finding was an ARID1A loss that was corroborated by molecular analysis showing an ARID1A deletion. The patient received systemic chemotherapy with carboplatin and paclitaxel protocol (Å ~ 4 cycles). Patient follow-up after the eighth month showed peritoneal implants predominantly in the right diaphragmatic cupule that were histologically confirmed as recurrence. She has just received another six cycles of chemotherapy with carboplatin and paclitaxel. Recognition of primary peritoneal clear cell carcinoma in this uncommon location, and exclude metastasis from the ovary, represents a diagnostic challenge.

Project description:IntroductionChromophobe renal cell carcinoma, a distinct subtype of renal cell carcinoma (RCC) with characteristic light microscopic, histochemical, and ultrastructural features, typically has a favorable clinical course.Presentation of caseA 45-year-old femele presented with abdominal pain. A physical examination found a palpable mass in the left upper quadrant of the abdomen. A CT scan of the abdomen showed a heterogeneously enhancing mass, with necrosis and calcifications contents betwen the liver and the right kidney. she underwent surgical resection. Partial nephrectomy was performed. Pathological diagnosis was Chromophobe renal cell carcinoma.Discussion and conclusionChromophobe RCC is a rare variety of kidney neoplasm that has recently been better characterized from a molecular and genetic perspective. Overall, it is considered to have a better prognosis, and is associated with earlier stage tumors and longer overall survival compared with clear cell RCC.

Project description:Bullous pemphigoid (BP) is a rare, life-threatening autoimmune blistering disease with pruritus and tension blisters/bullous as the main clinical manifestations. Glucocorticosteroids are the main therapeutic agents for it, but their efficacy is poor in some patients. Tofacitinib, a small molecule agent that inhibits JAK1/3, has shown incredible efficacy in a wide range of autoimmune diseases and maybe a new valuable treatment option for refractory BP. To report a case of refractory BP successfully treated with tofacitinib, then explore the underlying mechanism behind the treatment, and finally review similarities to other cases reported in the literature. Case report and literature review of published cases of successful BP treatment with JAK inhibitors. The case report describes a 73-year-old male with refractory BP that was successfully managed with the combination therapy of tofacitinib and low-dose glucocorticoids for 28 weeks. Immunohistochemistry and RNA sequencing were performed to analyze the underlying mechanism of tofacitinib therapy. A systematic literature search was conducted to identify other cases of treatment with JAK inhibitors. Throughout the 28-week treatment period, the patient experienced clinical, autoantibody and histologic resolution. Immunohistochemical analysis showed tofacitinib significantly decreased the pSTAT3 and pSTAT6 levels in the skin lesions of this patient. RNA sequencing and immunohistochemical testing of lesion samples from other BP patients identified activation of the JAK-STAT signaling pathway. Literature review revealed 17 previously reported cases of BP treated with four kinds of JAK inhibitors successfully, including tofacitinib (10), baricitinib (1), upadacitinib (3) and abrocitinib (3). Our findings support the potential of tofacitinib as a safe and effective treatment option for BP. Larger studies are underway to better understand this efficacy and safety.
