Multicentric myofibromatosis presenting as a large congenital eyelid myofibroma

Periorbital Myofibroma in a Child: A Case Report and Review of the Literature

Infantile myofibroma is a rare benign tumor usually diagnosed before the age of 2 and found in the head and neck but much more rarely in the orbital region. There have only been 7 cases of periorbital myofibromas reported in children in the literature to date. The current case is of an 8-year-old boy with a left upper eyelid myofibroma confirmed on histopathological and immunochemical analysis. A literature review of periorbital myofibromas has been performed to bring the reader up-to-date with the current understanding and management of the disease.

Solitary adult orbital myofibroma: Report of a case and review of the literature

Purpose

Myofibromas are benign soft tissue tumors commonly encountered in infancy and childhood. Developing usually within the first two years of life, they can be multicentric and involve deep visceral organs.

Observations

We present the rare occurrence of a solitary orbital myofibroma in an adult patient. The clinical, histopathologic and immunohistochemical findings of the tumor are documented.

Conclusions

A comprehensive review of pediatric and adult orbital and periocular involvement by myofibroma is presented. Its characteristic pathologic and molecular findings are reviewed.

Importance

Myofibromas are uncommon but important tumors that can occur in the head and neck region, including the orbit. Seen more often in children, they can rarely be encountered in adult patients. Diagnosis is possible with a panel of immunostains and molecular analysis can be further confirmatory.
