Aims. Metastatic malignant melanoma of the urinary bladder is a rare clinical entity, with only twenty-three published cases to date. We present a case of this rare entity, a thorough review of the literature, and differential diagnosis of melanoma in the bladder.Methods and Results. A 55-year-old woman with a history of malignant melanoma of the right thigh, excised eight years ago, presented with back pain, fatigue, and hematuria. She underwent computed tomography (CT) scan and was found to have metastases within the liver, spleen, lungs, and urinary bladder. She underwent cystoscopy and transurethral resection of three polypoid lesions. Histologic and immunohistochemical examination revealed metastatic malignant melanoma involving bladder mucosa.Conclusions. This case illustrates the importance of including malignant melanoma in the differential diagnosis of high grade neoplasms of bladder, especially in cases where the relevant clinical history is not available.

We describe the case of a primary cervical tumor in a 6-year-old child that was originally suspected to be an embryonal rhabdomyosarcoma botryoides. Histologic analysis revealed a clear cell adenocarcinoma. Despite a direct search and questioning for maternal exposure to diethylstilbestrol, this was not documented. Clear cell adenocarcinoma is an extremely rare neoplasm that should be kept in the differential diagnosis of cervicovaginal lesions in children, even in the absence of a clinical history of in utero diethylstilbestrol exposure. We discuss the hypothesized pathogenesis and review the literature on this unusual tumor.

The term gossypiboma is used to describe a retained surgical sponge after operation. It is a rare but serious complication which is seldom reported because of the medicolegal implications. Gossypiboma usually has varied and vague presentation and is also difficult to detect on radiological investigations. It can even remain silent and present years after the operation. We report a case of a 38-year-old lady who presented with vague pain and chronic lump in the right iliac fossa region. She had a history of cesarean section 4 years ago. Radiological investigations were inconclusive in detecting the retained sponge. A working diagnosis of mesenteric cyst was made and an exploratory laparotomy was done where she was found to have a large gossypiboma densely adhered to the small bowel and surrounding structures. Though rare, gossypiboma should be kept in mind as a differential diagnosis in postoperative cases presenting as vague pain or chronic lump even years after the operation.

Orbital Lesions

Orbital mesenchymal chondrosarcoma is a very uncommon lesion of the bone and extraskeletal tissue. To our knowledge, approximately 30 cases have been described. We present the case of a 52-year-old male who presented with a history of progressive proptosis and chemosis of the right eye caused by an orbital tumor. He underwent exenteration of the right orbit, and the histological examination revealed a mesenchymal orbital chondrosarcoma. This paper attempts to describe a rare entity that should be considered in the differential diagnosis of calcified orbital lesions, especially in young adults. Complete removal of the tumor is the mainstay of treatment, but adjuvant radiation therapy and chemotherapy should be considered.

Actinomyces meyeriis an uncommon cause of human actinomycosis. Here, we report a rare case of empyema caused byA. meyeri. A 49-year-old male presented with a history of 10 days of dyspnea and chest pain. A large amount of loculated pleural effusion was present on the right side and multiple lung nodules were documented on radiological studies. A chest tube was inserted and purulent pleural fluid was drained.A. meyeriwas isolated in anaerobic cultures of the pleural fluid. The infection was alleviated in response to treatment with intravenous penicillin G (20 million IU daily) and oral amoxicillin (500 mg every 8 hours) for 4 months, demonstrating that short-term antibiotic treatment was effective.

Abstract The identification of malignant melanoma in a visceral organ of nonepidermal origin is not an uncommon occurrence. Frequently, these cases are solitary metastases that present years after a thin epidermal melanoma has been diagnosed (and sometimes forgotten). However, primary visceral melanomas have been reported that have not been preceded by an epidermal lesion. We describe herein a unique case of melanoma presenting as a primary intrathymic tumor. The patient had no previous history of epidermal melanoma, and extensive workup did not reveal evidence for an alternative primary site. The tumor exhibited histologic features characteristic of melanoma, including an abundance of large pleomorphic cells with eosinophilic cytoplasm, prominent nucleoli, and occasional intranuclear inclusions. Tumor cells stained for HMB-45 and S-100 protein and ultrastructural analysis revealed stage II and stage III melanosomes. The patient remained free of disease until intrathoracic recurrence was detected on a computed tomographic scan 14 months later. The lack of clinical history and physical findings of melanoma at presentation, the intrathymic location of the tumor, and the pattern of recurrence suggest that this case likely represents a primary thymic melanoma, a previously unreported entity.

Abstract Introduction/Objective Filiform polyposis (FP), also referred as inflammatory polyposis or pseudopolyposis, is an uncommon benign entity usually diagnosed in patients with history of Crohn’s disease, ulcerative colitis, interstitial tuberculosis or histiocytosis X. It is characterized by multiple finger-like mucosal projections/pseudopolyps seen more commonly in transverse and descending colon. Pathogenesis of FP is uncertain but it is hypothesized to be reactive process to chronic inflammation leading to formation of fingerlike projections. The term filiform polyposis was coined in 1974 by Appleman HD and his collegues to describe numerous long slender worm-like (filiform) colonic lesions seen in radiographs. Herein, we are going to present a case of FP diagnosed in a 20-year-old male with history of medically refractive ulcerative colitis. Methods/Case Report The patient is a 20-year-old male, with a history of medically refractive ulcerative colitis on systemic steroids and vedolizumab. He underwent sigmoidoscopy and colonoscopy which reveals multiple pedunculated, polypoid lesions, ranging from 0.5 to 3 cm in length with white tips (cap of purulent mucous). Patient underwent total abdominal colectomy with end ileostomy. The specimen received by our deparment consist of a segment of right colon (63 cm in length, 3.5 cm in diameter) with attached ileum (3 cm in length, 2 cm in diameter) and appendix (6 cm in length, 0.8 cm in diameter). The part of the right colon is constricted/strictured measuring 24 cm in length, 2 cm in diameter. Opening reveals numerous (>100) pedunculated, finger-like polypoid lesions measuring from 0.3 cm to 2 cm in length. The lesions involve the entire right colon including distal colonic surgical margin. Appendix and ileum are not involved by the lesion and grossly unremarkable. Microscopic evaluation of the lesions reveal acute and chronic inflammatory cells, granulation tissue, areas of necrosis and reactive changes with focal mucosal atrophy consistent with chronic ulcerative colitis. Results (if a Case Study enter NA) NA Conclusion Filiform polyposis (FP) is an uncommon benign entity commonly seen in association with Inflammatory Bowel Diseases. Diagnosing FP requires comprehensive gross and microscopic examination as well as review of clinical history and imaginig studies. Because of its uncommon nature, we recommend to report this entity to raise awareness and to educate the pathologists who have not diagnosed it before.

Abstract Petrification of the auricle results in a rigid and immalleable ear. The etiology of such a finding is usually ectopic calcification. The condition has been associated with injurious processes, such as cold injury, and with various endocrinopathies, including Addison disease. In a significant number of cases, ossification occurs without knowledge of the precipitating cause or event. True auricular ossification is a rare occurrence, with only 12 histologically confirmed cases in the literature. We herein present the clinical and pathologic findings of another case. A 60-year-old man with diet-controlled diabetes presented with a 10-year history of slowly and insidiously stiffened auricles. He denied any precipitating historical events. Routine testing did not demonstrate systemic abnormalities. Radiographic examination revealed opacities consistent with bony structure in the auricles of the ears, with the right more prominent than the left. Histologic sampling demonstrated ossification with deposition of trabecular bone in proximity to normal elastic cartilage.

Primary Retroperitoneal

Ovarian dysgerminoma is a rare type of germ cell tumor. The majority of patient relapses occur within 2 years of diagnosis. Here, we report the case of a 74-year-old woman with a history of ovarian dysgerminoma 39 years earlier. The patient visited the hospital presenting with heartburn. An abdominal computed tomography (CT) revealed a right retroperitoneal mass, and a primary retroperitoneal tumor was suspected. She underwent surgical resection of the retroperitoneal tumor. Histological examination confirmed a metastatic dysgerminoma to the retroperitoneum. Postoperative CT showed paraaortic and cervical lymph node metastases. The patient was treated with bleomycin, etoposide, and cisplatin chemotherapy. This case demonstrates the difficulties that may be encountered in the differential diagnosis of a retroperitoneal mass and underlines the necessity for understanding a patient’s clinical history.
