1.Leiomyoma of the Skin: clinicopathological study of 19 cases.
Korean Journal of Pathology 1996;30(6):515-522
Nineteen cases of leiomyoma of the skin were examined clinicopathologically. This group included 12 cases of angioleiomyoma, 5 cases of solitary piloleiomyoma, and 2 cases of multiple piloleiomyomas. 1) All twelve angioleiomyomas occured as solitary lesion in the extremities. There was a preponderance in females with a ratio of 2:1. The ages of patients ranged from 24 to 80 years and only one was below the age of 30 years. Six tumors were either painful or tender. Nine tumors in subcutaneous fat were shelled out at surgery. All tumors did not exceed 4cm in diameter. Histologically they could be separated into ten cases of the solid type and two cases of venous type according to Morimoto's classification. Although actin or desmin was easily detected in all tumors, the diagnosis was better made using a combination of hematoxylin-eosin and Masson trichrome stains. 2) Five cases of solitary piloleiomyoma were slow-growing intradermal nodules. The ages of patients ranged from 10 to 77 years. All five cases were female. The lesions were located on the extremities, back and sholuder. Pain or tenderness was present in 3 cases among these tumors. Histologically, all tumors were characterized by subtle poorly circumscribed proliferation of benign smooth muscle in the dermis. 3) Two multiple piloleiomyomas from two female patients, aged 50 and 40 years, were situated on the shoulder and thigh, respectively. Pain was induced by change of temperature in the shoulder lesion. Histologically they were identical to the solitary piloleiomyoma.

Tubular apocrine adenoma is a rare benign tumor occuring most often on the scalp. We examined a case of a 69-year-old female who had a well demarcated solid nodule on the scalp. Pathol Microscopically, the tumor was composed of lobules of tubular structures. The tumor lobules were surrounded by a stroma of dense fibrous connective tissue. The tubular structures were usually formed of two rows of epithelial cells. In some areas, the widely dilated tubular structures showed papillary projections into the cavities. Some epithelial cells showed liculoma on decapitation secretion into the cystic structure. Problems of differential diagnosis with other adnexal tumors are briefly discussed.

Sebaceous trichofolliculoma is a variant of trichofolliculoma which occurs in the sebaceous areas rich in follicles and is a relatively rare skin tumor. This tumor is a clinically and histologically easy tumor to recognize that is well differentiated. We examined a case of a consists of a 21-year-old female who had a pedunculated nodule on her scalp. Microscopically, the tumor was large, had a centrally located cavity lined by squamous epithelium and radially arranged sebaceous follicles connected to the cavity. No cytological atypia or recurrence after excision was found.

Arteriovenous malformation of the uterus is rarely encountered. It is potentially lethal because of profuse, uncontrollable bleeding at the time of diagnostic dilatation and curettage. To our knowledge, only 38 cases of localized uterine arteriovenous malformation have been reported in English and Korean literature. Recently we experienced a case of uterine arteriovenous malformation in a 28-year-old multiparous woman. Under the clinical impression of uterine tumors or arteriovenous malformation, a total hysterectomy was done. Gross examination demonstrated a vascular nature of the mass in the posterior wall of the fundus. Microscopically, there was an ill-defined mass composed of numerous irregular, anastomosing large vessels with various diameters.

The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.

Gatric duplication is a rare congenital anomaly. Thus for about 90 cases of gastric duplication have been recorded in the literature. It is less frequent than small intestinal or eosphageal duplication, and accounts for only 3.8% of all gastrointestinal tract duplication. Most gastric duplications are seen during the first year of life. Palpable abdominal mass and gastric outlet obstruction in infancy are most common presentation. We experienced a case of non-communicating gastric duplication. A 12-year-old girl visited St. Mary's Hospital because of indigestion, intermittent vomiting, and left upper quandrant pain for about 40 days. She have had intemittent abdominal pain with concomitant increased level of amylase since 5 years old. Physical examination showed a hen's egg sized palpable mass on left upper quadrant of the abdomen. Upper GI series and barium enema revealed only indentation of duodenal C-loop, and sonogram and abdominal CT demonstrated isolated cystic mass along the greater curvature of gastric antrum. She had taken an operation under the impression of pancreatic pseudocyst. Operation revealed a cystic mass, located along the greater curvature. There was no pathologic change in the pancreas. Microscopic findings of the cyst wall revealed normal gastric mucosal lining and common muscle layer, shared with gastric antral muscle layer.
