Carotid body paraganglioma is a neuroendocrine neoplasm of the mandibular region. Due to its prominent stromal alternations, carotid body paraganglioma is a great emulator of other neoplasms in the head and neck region especially in metastatic tumors and its definite diagnosis is a great challenge. To the best of our knowledge, the most frequently reported variant is sclerosing and paragangliom...

A case of sclerosing stromal tumor of the ovary in a 16-year-old girl is described. The lesion had the characteristic mixed pseudolobular pattern with cellular areas separated by edematous stroma. A prominent, additional feature was the presence of partially or completely obstructed vessels at the hilus. It is proposed that these vascular changes may be the cause of the edema in the tumor.

Sclerosing stromal tumours of the ovary have recently been described as a histologically and clinically distinct subgroup within the thecoma-fibroma spectrum of benign ovarian sex cord stromal tumours. Reported cases occurred predominantly in young women and only occasional tumours showed evidence of hormonal activity. The present series of five cases expands the spectra of both histological pa...

gastrointestinal stromal tumors (gist) are the most common mesenchy­mal tumors of the gastrointestinal tract. the biological pattern of these tumors ranges from benign-appearing small lesions to malignant sarcomas. only 3%-5% of gists are found in the duodenum. a duodenal gist is a rare source of upper gastrointestinal bleeding. a remarkable percentage of duodenal gists are localized in the thi...

Sclerosing Adenosis (SA) is a lobulocentric proliferative process that involves both the epithelial and the mesenchymal component of the breast suggesting benignity. The disease has an increased incidence among reproductive-age and perimenopausal women, especially be age. The clinical, radiological, and histopathological properties of sclerosing adenosis may resemble malignancy, which is the fa...

Sclerosing stromal tumour (SST) is a rare benign sex cord stromal tumour of the ovary. We report a case of sclerosing stromal tumour of the mesentery in a 32-year-old Para one who presented with intra abdominal mass, menstrual irregularity and secondary infertility. Histopathology and immunohistochemistry of the completely excised tumour was consistent with sclerosing stromal tumour, immunoreac...

BACKGROUND Mammary sclerosing lobular hyperplasia is an uncommon benign lesion of adolescent and young women. Fine-needle aspiration cytology of mammary sclerosing lobular hyperplasia is said to show characteristic features that include an absence of stromal fragments. CASE PRESENTATION In this article, we describe a case of sclerosing lobular hyperplasia that occurred in the right breast of ...

A sclerosing stromal tumor of the ovary is an extremely rare benign tumor; it usually is found during the second and third decades of life. Patients present with pelvic pain or a palpable abdominal mass. Hormonal effects such as masculinization are uncommon. Here, an 11-year old premenarchal girl presented with deepening of the voice. In addition, clitoromegaly and hirsutism with a male suprapu...

Pulmonary sclerosing hemangioma is an uncommon benign tumor of the lung; however, on rare occasions it can arise from the pulmonary hilar region. Herein, we report a 53-year-old female patient who presented with a round opacity in the right upper lung field on a radiograph. Chest computed tomography scanning revealed a 3.1 cm mass in the right pulmonary hilum. Thoracoscopic tumor excision was s...

Sclerosing stromal tumor (SST) is an extremely rare and distinctive sex cord stromal tumor, occurring predominantly in the second and third decades of life. In this article, our aim is to present clinicopathologic features of STT, and to review the recent literature with regard to differentiating STT from other ovarian stromal tumors. We describe STT in a 17-year-old girl who presented with an ...
