Cutaneous leiomyoma-a clinical and histopathological study / 대한피부과학회지

ABSTRACT

We reviewed 50 skin biopsies obtained from 40 patients with cutaneous leiomyoma during a 10 year period from January 1980 to December 1989. The result.s were summarized as follows 1) Sex distribution showed a female preponderance with male.female ratio of 1 1.9. 2) The age distribution was relatively even from childhood to old age. The mean age was 47,8 years, 3) The most common site of lesion was lower leg(34%) followed by hand(24%), foot(12% ), anterior chest(8% ), face(6% ), neck(4%), upper arm(4% ), labia major(2 %) and nipple(2%). 4) The lesions were relatively well circumscribed subcutaneous nodule, papule, plaque and nodule which measured between 0.3cm to 5cm in size and their colors were erythematous to light brown. 5) The most common clinical and histopathologic type was angioleiomyoma(75%) followed by solitary piloleiomyoma(12.5%), multiple piloleiomyoma(7,5%) and solitary genital leiomyoma(5% ). Angioleiomyomas were clincally associated with cavernous hemangioma, myoma of uterus and systemic lupus erythematosus. 7) The clinical diagnoses were mass(30% ), epidermal cyst(20%), dermatofibroma (12.5% ), leiomyoma(12,5%), neurilemmoma(5%), lipoma(5%), calcifying epithelioma(2.5%), metastatic carcinoma(2.5%), morphea(2.5% ), fibrocystic disease(2.5%), glomus tumor(2.5 % ) and Dupuytrens contracuture(2..5%).
