A Case of Solitary Cutaneous Myofibroma of the Thigh in An Adult.: Jung Hwan Park, Chang Woo Lee, Young Chae Chu, Moon Hyang Park; Korean J Pathol. 2001;35(4):354-356.

Abstract PDF: Adult solitary cutaneous myofibroma is a recently described benign neoplasm of the skin or subcutis, representing the adult counterpart of infantile myofibroblastoma. The histologic and immunohistochemical features of a 21-year-old woman with a solitary brownish, mildly tender nodule on her right thigh are reported here. The nodule had been present for a duration of 3 years. It showed a nodular dermal mass with an irregular margin. The lesion consisted of interlacing bundles of spindle cells which were positive for smooth muscle actin, muscle specific actin and vimentin. Immunohistochemical stainings for desmin, S-100 protein, CD 34 and CD 68 were negative. Cutaneous myofibroma in an adult is a distinct entity of benign neoplasm.

Infantile Myofibromatosis(Congenital Generalized Fibromatosis): Associated with multiple congenital malformations and basaloid follicular hamartomas in the skin.: Eun Sook Nam, Yoo Hun Kim, Han Kyeom Kim, Insun Kim, Je Geun Chi; Korean J Pathol. 1995;29(6):776-782.

Abstract PDF: Infantile myofibromatosis with systemic involvement is a very rare disease and is characterized by numerous nodules composed of spindle cells of a myofibroblastic nature. There are often disseminated throughout the subcutis, muscle, skeleton and viscera. We report an autopsy case of infantile myofibromatosis in a stillborn female fetus of 32 weeks of gestation. The nodules, Imm to 2 cm, were found over the whole body and viscera. The involved viscera were the heart, tongue, esophagus, gastrointestinal tract, portal areas of the liver, spleen anc pancreas. There were also associated malformations, viz., frontal meningoencephalocele, flexion defer-mities, syndactyly, cleft palate, agenesis of corpus callosum, pachygyria, diaphragmatic hemia, renal hypoplasia, etc. Multiple basaloid follicular hamartomas of the skin were noted on the face and extremeties. There are no previous reports in the literature of infantile myofibromatosis in conjunction with the above skin lesion and congenital malformations.
