Carcinosarcoma of the stomach is a rarely occurring malignant biphasic tumor that consists of both carcinomatous and sarcomatous components simultaneously in a single tumor. The common carcinoma component is tubular or papillary adenocarcinoma and the mesenchymal sarcomatous components are variable and these include leiomyosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma. However, neuroendocrine carcinomatous differentiation in the carcinomatous component is extremely rare. We present here a rare gastric carcinosarcoma that demonstrated neuroendocrine carcinomatous and leiomyosarcomatous differentiation in a 47-year-old man.

Myxoma of the Larynx Presenting As a Nodule.: Young Soo Song, Si Hyong Jang, Kyueng Whan Min, Woong Na, Se Min Jang, Young Jin Jun, Seung Sam Paik; Korean J Pathol. 2008;42(5):306-307.

Abstract PDF: We describe herein a rare case of a laryngeal myxoma presenting as a nodule. Laryngeal myxomas involving the neck region, especially the laryngeal area, are quite rare. A 36-year-old male patient presented with a 2 month history of hoarseness. On laryngoscopic examination, there was a myxoid homogeneous transparent mass on the right vocal cord. On microscopic examination, the lesion was hypocellular and myxoid. The lesion showed stellate or spindle cells which were evenly dispersed in the poorly vascularized myxoid stroma. Although the incidence is extremely rare, a laryngeal myxoma should be considered in the differential diagnosis of laryngeal masses.

Abstract PDF: Hairy polyps are a rare malformations of bigerminal origin that comprise of both ectodermal and mesodermal elements. Meningothelial elements are an extremely rare pathologic finding in hairy polyps. Here we report a case of a hairy polyp with a meningothelial element, which originated from the hard palate. A 1-year-old boy was evaluated for an intraoral mass accompanied by multiple congenital anomalies. A small polypoid mass was noted at the midline of the hard palate. The lesion had central fibroconnective tissue with an unusual stromal component showing reticulated anastomosing pseudovascular patterns. Immunohistochemical staining of the cells lining the pseudovascular spaces and the interstitial cells revealed vimentin and epithelial membrane antigen positivity.

Abstract PDF: Cystic lymphangioma is also known as cystic hygroma, and this is a congenital malformation of the lymphatic system. Most lymphangiomas are present at birth and they are diagnosed by the age of 2. They are mostly located in the neck or axillary region. The breast as a site of origin is an extremely unusual location, and especially in adults. We report here on a case of cystic lymphangioma in a 36-year-old woman. Physical examination revealed a tender cystic mass in the upper outer quadrant of the right breast. Ultrasonography revealed an irregular hypoechoic mass lesion that was associated with irregular duct dilatation and several enlarged axillary lymph nodes. After the operation, the mass was revealed to be a cystic lymphangioma. Although it is very rare, cystic lymphangioma should be considered in the differential diagnosis of a breast mass in adults.

The Intestinal Type of Florid Cystitis Glandularis Mimics Bladder Tumor: A Case Report.: Young Soo Song, Ki Seok Jang, Si Hyong Jang, Kyueng Whan Min, Woong Na, Soon Young Song, Hong Sang Moon, Tchun Yong Lee, Seung Sam Paik; Korean J Pathol. 2007;41(2):116-118.

Abstract PDF: Cystitis glandularis is a benign metaplastic proliferative lesion of the urinary bladder which usually occurs in the setting of chronic irritation and infection or in some cases as a congenital process. Sometimes it presents as a tumor mass-like florid lesion, grossly mimicking malignancy. We report a case of 59-year-old man with multiple mass lesions around the trigone and the neck portion, which suggested the possibility of malignancy in clinical and radiological evaluations. Final diagnosis was confirmed by transurethral resection. The surface urothelial lining was intact. The submucosa showed von Brunn's nests, cystitis glandularis and cystitis cystica in the edematous lamina propria. There were numerous glands lined by tall columnar, mucin producing epithelium without atypia, conforming to the appearance of the intestinal variant of cystitis glandularis. The cystitis glandularis may mimic a neoplasm on gross evaluation. The intestinal variant of cystitis glandularis is particularly likely to be problematic when florid.

Kikuchi's Disease of the Mesenteric Lymph Nodes Presenting as Acute Appendicitis.: Kyueng Whan Min, Ki Seok Jang, Si Hyong Jang, Young Soo Song, Woong Na, Soon Young Song, Seung Sam Paik; Korean J Pathol. 2007;41(1):44-46.

Abstract PDF: Kikuchi's disease is a benign self-limiting necrotizing lymphadenitis that occurs most commonly in young women, and is usually found in the cervical lymph nodes. When there is an unusual location of involved lymph nodes, the diagnosis can be difficult. We recently treated a patient with Kikuchi's disease who had ileocecal mesenteric lymph node involvement; the patient presented with symptoms of acute appendicitis in an 11-year old boy. Although mesenteric lymph node involvement of Kikuchi's disease is very rare, Kikuchi's disease should be added to the differential diagnosis of acute appendicitis in patients with enlarged ileocecal mesenteric lymph nodes on radiological evaluation.
