1/88. Cutaneous angioleiomyoma.

    Leiomyomas are smooth-muscle tumors that may be encountered in the practice of podiatric medicine when they affect the arrector pili muscles or the smooth muscle of a vessel wall. In the present case, the lesion was located on the heel, an area with no hair growth; this further supports the diagnosis, as the most likely origin of the lesion was the smooth muscle of a blood vessel. Vascular leiomyomas show a greater predilection for the lower extremities than their superficial counterparts. Surgical excision is the treatment of choice for these benign lesions, whose prognosis is excellent. When a patient presents with a painful mass in the lower extremity, the diagnosis of leiomyoma should be considered. ( info)

2/88. Intravascular angioleiomyoma.

    A 59-year-old man presented with a 6-year history of a 2-cm tender nodule on his left lateral elbow. Excisional biopsy led to the diagnosis of angioleiomyoma. However, unlike typical angioleiomyoma which demonstrate extravascular extension, this lesion demonstrated purely intravascular growth. ( info)

3/88. Multiple piloleiomyomas associated with solitary angioleiomyoma.

    A 58 year-old male had reddish scattered papules strictly confined to the right side of his upper back and neck, right shoulder, and right upper arm. Additionally, he also noticed a subcutaneous nodule on his left thigh. Histopathological examinations revealed that the papules on the back, nape of the neck, shoulder, and arm were multiple piloleiomyomas, as shown by the proliferation of bundles of smooth muscles in the dermis. The subcutaneous nodule of the thigh was angioleiomyoma with a well-circumscribed lesion composed of smooth muscles and blood vessels. Ipsilaterality and segmentality of the distribution of the papules of piloleiomyomas and probable family history that his mother had similar papules with a similar distribution suggest the nevoid character of our case. Piloleiomyomas are often reported to be associated with leiomyoma of the uterus or other organs. This is the first reported case of multiple piloleiomyomas with solitary angioleiomyoma in the literature. ( info)

4/88. Angiomyofibroblastoma of the female urethra.

    BACKGROUND: Angiomyofibroblastoma is a relatively recently described rare tumor of the superficial soft tissues. To date, 57 cases of angiomyofibroblastoma of the external genitalia in women have been reported. methods/RESULTS: We describe a case of a 24-year-old woman who presented with the urinary stream flowing out in the posterior direction and whose diagnosis was a urethral tumor, angiomyofibroblastoma. CONCLUSIONS: Angiomyofibroblastoma has a potential arising from the female urethra as well as other areas of the external genitalia. ( info)

5/88. Perineal angiomyofibroblastoma: CT and MR findings with pathologic correlation.

    We present a case of a perineal angiomyofibroblastoma (AMFB) arising in the right perirectal fossa in a middle-aged woman, documented with CT and MRI. Compounding the rarity of the entity, this case is unique as it is the first radiological report illustrating the CT and MR features of this recently clinicopathologically described neoplasm.

6/88. Primary angioleiomyoma of the iliac bone: clinical pathological study of one case with flow cytometric dna content and S-phase fraction analysis.

    We report on a primary angioleiomyoma of the right iliac bone in a 28-year-old woman. To our knowledge this is the 16th reported case of a primary leiomyoma of bone, the 9th reported primary osseous angioleiomyoma and the first description of a primary angioleiomyoma located in the iliac bone. The problems of differentiating primary leiomyoma of bone from primary or metastatic leiomyosarcoma of bone are stressed. A literature review of primary leiomyomas of bone is presented. ( info)

7/88. Pleomorphic angioleiomyoma.

    We describe two cases of pleomorphic angioleiomyoma. In one case, a 46-year-old man presented with a single nodule on his scrotum of 1 year's duration, and in another, a 38-year-old woman presented with a single nodule on her right knee of 1 year's duration. In both cases, histopathologic examination showed a well-circumscribed nodule composed of smooth muscle and numerous veins and capillaries. Contrary to the ordinary angioleiomyoma, marked nuclear pleomorphism was noted. Although mitoses were rare, immunohistochemistry revealed many tumor cells that were positive for proliferating cell nuclear antigen, Ki-67, and p53, indicating that the pleomorphic appearance does not simply represent a degenerative change of some tumor cells.

8/88. Angioleiomyoma of the diaphragm.

    We report a case of a large symptomatic angioleiomyoma of the diaphragm. The tumor was diagnosed by computed tomography and videothoracoscopic biopsy. We removed the tumor through a left thoracolaparotomy. Three months later, a local recurrence was removed through an upper midline laparotomy. The patient remains without evidence of a recurrence 48 months after the second operation. ( info)

9/88. angiomyoma of the knee joint: value of magnetic resonance imaging.

    A case of angiomyoma as an unusual cause of knee pain is presented and the usefulness of magnetic resonance imaging in such a situation is discussed. ( info)

10/88. Angiomyomatous hamartoma and associated stromal lesions in the right inguinal lymph node: a case report.

    Angiomyomatous hamartoma is a rare disease with a predisposition for the inguinal lymph nodes. A 51-year-old male patient visited a local hospital because of a right inguinal mass, measuring 3 x 4 cm in size, which was resected. The resected specimen showed irregularly distributed thick-walled vessels in the hilum, extending into the medulla and focally into the cortex of the node, eventually becoming more dispersed and associated with smooth muscle cells splaying into sclerotic stroma. These findings are compatible with an angiomyomatous hamartoma. Another tumor-like mass appeared shortly after the resection at the same location, but was not an angiomyomatous hamartoma, rather it was composed of edematous stromal tissue with proliferating smooth muscle cells. The stromal component included thick-walled blood vessels and lymphatics. Although it could not be determined whether these associated changes in the surrounding stroma are a cause or an effect of angiomyomatous hamartoma, they indicate the clinical difficulty in determining an appropriate area of resection and may provide clues to the pathogenesis of angiomyomatous hamartoma.
