Myoepithelial neoplasms of the soft tissues are a rare, heterogeneous group of tumors for which classification continues to evolve. While well defined within salivary glands, they can also arise in viscera and soft tissues, where diagnosis is challenging due to the lack of clinical and pathological familiarity. We present the case of a 36 year old man with myoepithelial carcinoma arising as a p...

We report a case of double uterine tumor resembling ovarian sex cord tumor (UTROSCT). The tumor was composed of sex cord-like cords, nests and tubules, and bundles of myoid cells. The lesion was interesting especially in regard to histogenesis of intratumoral myoid cells. It is not known whether these cells are neoplastic or whether they represent preexisting myometrial smooth muscle cells entr...

Neurilemmoma is a benign slow-growing nerve sheath neoplasm that is rarely found in the female genital system. To date, thirteen cases of vulvar neurilemmoma have been reported in the world literature. We report here on the first Korean case of vulvar neurilemmoma. A 43-year-old woman presented with a 0.6×0.6 cm sized oval nodule at the left labium minus. Complete excision was done. Microscopic...

Abstract Malignant melanoma is an aggressive neoplasm with a high tendency to metastasize. Gastrointestinal metastases, although described in the literature, are infrequent. We present case of 51-year-old male patient surficial spreading stage IIIc BRAF mutation who presented gallbladder outgrowth lesion, compatible polyp. A significant growth lesion was observed subsequent TC studies and lapar...

Kidney mucinous tubular and spindle cell carcinoma (MTSpCC) is a rare renal low-grade pleomorphic epithelial neoplasm featured by tubular and spindle cells with a relatively indolent behavior. This study was designed to clinicopathologically characterize two cases of kidney MTSpCC. Similar to other tumors, the data showed the diagnosis of MTSpCC relies on histological examination. Tumor cells s...

inflammatory myofibroblastic tumor is an uncommon benign neoplasm and its presentation in small bowel is rare. due to clinical manifestation, laboratory data and radiologic results, there is an increased risk of over diagnosis as malignant tumors particularly malignant lymphoma in childhood therefore may be resulting in wrong therapeutic approach. however pathologic findings could be demonstrat...

Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm that can be potentially low malignant and mainly affects infants and adolescents. This tumor usually is seen in the skin, soft tissue, and retroperitoneum. This study is a case of KHE in the long bone of the ulna. The subject was a 7-year-old female patient with osteolytic lesion in the forearm without cutaneous lesions. Histolog...

Pulmonary spindle cell proliferations have been reported in association with a limited group of infectious agents. These lesions are rare and identified most often in the setting of immunosuppression. Because their appearance can simulate a spindle cell neoplasm, they are diagnostically treacherous, sometimes delaying antimicrobial therapy or resulting in unnecessary surgery. We report a case o...

Thyroid nodules are uncommon in childhood and recurrent thyroid nodules even rarer. Spindle epithelial tumor with thymus-like differentiation (SETTLE), a rare and distinctive low-grade neoplasm is amongst the differential diagnosis of solitary thyroid nodule in children. We describe a boy who underwent completion thyroidectomy for SETTLE in the thyroid remnant four years after initial lobectomy...

Solitary fibrous tumour (SFT) is a rare, spindle-cell, mesenchymal neoplasm with haemangiopericytoma-like branching vascular pattern. The tumour has been reported in various locations but the oral cavity is a distinctly uncommon region. We describe a case of solitary fibrous tumour (SFT) in the tongue of a 15-year-old girl. Microscopically it had features characteristic for SFT and a common imm...
