Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

We described the findings of fine needle aspiration cytology of the lung from a patient with Wegener's granulomatosis. Early diagnosis and prompt treatment of the patients with Wegener's granulomatosis is essential for a better prognosis. However, the variety of clinical presentations and nonspecific radiologic infiltrates of Wegener's granulomatosis frequently make the diagnosis difficult. Although an open lung biopsy is required for a firm diagnosis, fine needle aspiration cytology & biopsy preparation can also provide an adequate tissue sample, when the findings of fine needle aspiration are considered with clinical manifestations and ANCA value in the serum. The cytologic smears showed scattered necrotic tissue fragments entrapping many neutrophils and occasional epithelioid cells. Multinucleated giant cells were infrequently observed. Ziehl-Neelsen stain for acid fast bacilli was negative. All the cytologic features recapitulated the histopathologic findings of purulent and necrotizing granulomatous inflammation seen in Wegener's granulomatosis.
