Cutaneous leiomyoma: novel histologic findings for classification and diagnosis. (25/28)

Smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. This study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better classification and diagnosis. The six year data base of our center was reviewed and 25 patients with cutaneous leiomyoma were included in this study. Of 25 patients, 5 were female and 20 were male. 5 patients had angioleiomyoma (ALM) and 20 had pilar leiomyoma (PLM). ALM had following characteristics: dilated vascular canals intermingled with compact smooth muscle bundles; well circumscribe counter and myxoid and hyaline changes through the tumor. In contrast, PLMs had following histologic features: poor defined outline, entrapped hair follicles and eccrine glands, acanthosis and elongated rete ridges with hyperpigmentation and smooth muscle bundles which are interdigitated with elongated rete ridges. Here we introduced some distinct histological features for each subtype of the cutaneous leiomyoma which can lead to create novel criteria for classification and diagnosis of the lesion.  (+info)

Angioleiomyoma in a rare location: a case report. (26/28)

A case report of a 38-year-old man with a 10 year history of left buttock mass associated with pain and numbness. A computed tomography scan showed a subcutaneous enhancing 1cm lesion that was not communicating with surrounding structures to include neurovascular structures. The mass was removed without complication and sent to pathology for extensive review. This case report signifies the importance of maintaining a broad differential with a subcutaneous mass presentation and includes thorough histology and pathology for angioleiomyoma.  (+info)

Angioleiomyoma of the nasopharynx in a dog. (28/28)

A polypoid angioleiomyoma was surgically removed from the nasopharynx of a 1-year-old, male golden retriever. The polypoid mass recurred 4 months later and was again excised. There was no sign of regrowth 13 months postoperatively. This is, apparently, the first reported angioleiomyoma occurring in the dog.  (+info)
