Plaque-like Myofibroblastic Tumor: 2 Cases of This Unusual Dermal Tumor Which Occurs in Infancy and Early Childhood

Plaque-like myofibroblastic tumor (PLMT) is a rare dermal spindle cell tumor which occurs in infancy or childhood within the first 4 years of life. The tumor is often pruritic and mostly presents on the lower back. We describe 2 cases with characteristic clinical and histological features of this entity, thus adding to the 10 cases which have so far been reported. Histologically, the lesion resembles a dermatofibroma. However, diffuse and uniform immunohistochemical staining with smooth muscle actin favors a myofibroblastic lineage. PLMT should be considered in the differential diagnosis of a dermal spindle cell tumor in the pediatric age-group.

“…DF usually presents in adults as a small nodular lesion (generally <1 cm in size), most often located on the lower extremities. It presents as several clinical and histopathologic variants, such as multiple clustered DF, although multiple clustered DF is a rare variant that has been reported in children and young adults and usually appears in the first and second decades of life , although congenital and infancy‐acquired cases of multiple clustered DF have been reported in the literature .…”

Plaque-like myofibroblastic tumor of infancy is a rare entity, with only a few reports described in the literature. Herein we present a new case of a nodular plaque-like lesion of the left lower back in an 18-month-old boy. The lesion might initially be thought to be a dermatofibroma, but the overall characteristics suggested the diagnosis of plaque-like myofibroblastic tumor of infancy. We also provide a summary of previous reports in the literature about this exceptional tumor.

Multiple clustered dermatofibroma (MCDF) is an unusual variant of dermatofibroma (DF) presentation, localized on one segment of the body. Multiple dermatofibroma is a term for when there are more than 15 dermatofibromas, which in itself is already a rare condition. The dermatofibromas usually appear in younger adults and are predominantly located on lower parts of the body. No associations, except one case with pulmonary hypertension, were described in patients with MCDF. Herein we present another case of this rare complaint in a 58 year old female with clustered lesions on the thigh. Pericardial cyst was identified in our patient during routine chest X-ray and the patient is asymptomatic. MCDFs do not usually require treatment unless requested by the patient for cosmetic reason. This variant of MCDF, which is neither congenital nor eruptive, is extraordinarily rare, with only 13 cases reported. Further reports may identify possible associations of MCDF.Keywords: Dermatofibroma; histiocytomas; pericardial cyst Citation: Brzezinski P, Kazlouskaya V, Bimbi C.
