Plaque-like myofibroblastic tumor, a rare entity of childhood: Possible pitfalls in differential diagnosis.

J Cutan Pathol 2019 May 22;46(5):389-392. Epub 2019 Mar 22.

Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Bologna, Italy.

Plaque-like myofibroblastic tumor is a rare and benign pediatric soft tissue tumor. It presents as a slowly growing plaque reaching several centimeters in diameter, made up of multiple nodules. The clinical and histological features of this benign entity are similar to other fibrohistiocytic or myofibroblastic tumors occurring in childhood, so the diagnosis can be difficult. Read More

Plaque-like myofibroblastic tumor of infancy was first characterized in 2007 by Clarke et al. In the first 2 cases described, large plaque-like tumors presented in the first 3 months of life exhibited microscopic features consistent with dermatofibroma but with immunohistochemical features of myofibroblastic lineage. In 2013, Marqueling et al reported 3 additional cases, 2 of which presented in early childhood, prompting the authors to recommend that the name of this condition be shortened to plaque-like myofibroblastic tumor.

Plaque Like Giant Dermatofibroma: A Case Report.

J Cutan Aesthet Surg 2017 Jan-Mar;10(1):51-53

Department of Pathology, Amrita Institute of Medical sciences, Amrita univerisity, Kochi, Kerala, India.

Dermatofibroma, also known as benign fibrous histiocytoma, is a soft-tissue tumour that usually occurs in the mid-adult life and shows a slight female predominance. Giant dermatofibroma, a very rare clinical variant, is characterised by its unusually large size, benign biological behaviour despite its large size and same histopathological characteristics as conventional dermatofibroma. We report a 63-year-old woman who presented with a large tumour on the scapular region which showed histopathological features of benign dermatofibroma. Read More

Plaque-Like Myofibroblastic Tumor of Infancy: A New Case Report and Literature Review.

Pediatr Dermatol 2017 Mar 16;34(2):176-179. Epub 2016 Dec 16.

Department of Molecular Medicine, Sapienza University of Rome, Azienda Policlinico Umberto I, Rome, Italy.

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. Read More

Plaque-like myofibroblastic tumor: report of three cases.

Pediatr Dermatol 2013 Sep-Oct;30(5):600-7. Epub 2013 Jul 12.

Department of Dermatology, University of California at San Francisco, San Francisco, California.

Plaque-like myofibroblastic tumor of infancy (PMTI) was first reported in 2007. The first two cases described large, plaque-like tumors presenting in infancy with microscopic features consistent with dermatofibroma but with immunohistochemical features of myofibrocytic lineage. We present three additional cases of PMTI, the first cases reported since the initial two cases, and describe additional clinical features of this condition, including presentation in early childhood as opposed to infancy, development of ulceration, and aggressive growth.

Two cases of dermatomyofibroma (plaque-like dermal fibromatosis).

Int J Dermatol 2010 Aug;49(8):914-7

Department of Dermatology, Carlos Haya Hospital, Malaga, Spain.

Background: Dermatomyofibroma is a rare but distinct benign cutaneous mesenchymal neoplasm of fibroblastic/myofibroblastic differentiation. It is more common in adolescents and young adults, with a female preponderance. In most cases, the lesions are asymptomatic and small, measuring from 10 to 20 mm. Read More

Atypical fibroxanthoma: a histological and immunohistochemical review of 171 cases.

Am J Dermatopathol 2010 Aug;32(6):533-40

Cutaneous Pathology, Western Australia, Australia.

The clinical and histological features of 171 atypical fibroxanthomas (AFX) from a single institution in Western Australia are outlined. This area experiences high levels of solar radiation, and all assessable biopsies showed solar elastosis. Patients were aged between 41 and 97 years (median age 74), with 76% of tumors occurring in men (male to female ratio approximately 3 to 1). Read More

Plaque-like dermatofibroma: A distinct and rare benign neoplasm?

Australas J Dermatol 2008 May;49(2):106-8

Austin Health, Heidelberg, Australia.

Unusual large dermatofibromata are reported in a 40-year-old man and a 48-year-old man, who both presented with plaques on a lower limb. The largest plaque in each case was well-defined, reddish brown, indurated and measured 50 mm x 30 mm and 70 mm x 40 mm, respectively. Several satellite lesions were present around the large plaques.

Plaque-like myofibroblastic tumor of infancy.

Pediatr Dermatol 2007 Sep-Oct;24(5):E83-7

Department of Dermatology, Penn State Milton S. Hershey Medical Center, Hershey, Pennsylvania 17033, USA.

Fibrohistiocytic neoplasms are relatively uncommon in infancy and childhood. We report an unusual spindle cell tumor occurring in two infants within the first 3 months of life. These tumors histologically resembled dermatofibromas, but the young age of onset, large size, and plaque-like morphology were distinctly different from those of dermatofibromas. Read More

Histopathology 2003 Jun;42(6):594-8

Dermatopathologisches Gemeinschaftslabor, Friedrichshafen, Germany.

Aims: Dermatomyofibroma (plaque-like dermal fibromatosis) represents a distinct clinicopathological entity in the spectrum of cutaneous mesenchymal neoplasms showing a myofibroblastic line of differentiation. These benign neoplasms occur frequently, but not exclusively, in young women, and the shoulder girdle as well as the upper trunk are common locations. Histologically, dermatomyofibroma is characterized by a plaque-like proliferation of cytologically bland spindle-shaped tumour cells containing an ill-defined, pale eosinophilic cytoplasm and elongated, neuroid nuclei.

Dermatomyofibroma: a report of two cases, one occurring in a child.

Australas J Dermatol 2001 Feb;42(1):22-5

Sullivan and Nicolaides Pathology, PO Box 344, Indooroopilly, Old 4068, Australia.

Dermatomyofibroma is a recently described plaque-like dermal tumour composed of myofibroblasts that usually presents around the shoulder, axilla and posterior neck, often in young adult females. Here, we present two cases, one from the posterior axilla of a 33-year-old female and one from the posterior neck of a 7-year-old male. Both were clinically red-brown lesions with histological and immunohistochemical features diagnostic of dermatomyofibroma. Read More

[Differences between plaque-like variants of dermatofibrosarcoma protuberans and plaque-like dermal fibromatosis (dermatomyofibroma)].

Hautarzt 1994 May;45(5):299-303

Dermatohistologisches Labor Friedrichshafen, Westfälischen Wilhelms-Universität Münster.

On the basis of two cases the differences between the plaque-like variant of dermatofibrosarcoma protuberans (PDFSP) and the plaque-like dermal fibromatosis (synonym: dermatomyofibroma; PDF) are presented. PDFSP and PDF are two clinically very similar dermal fibrous proliferations, but differentiation is important because of their different therapy and prognosis. Histologically and immunohistochemically PDFSP and PDF can be recognized as separate entities. Read More

Dermatomyofibroma: additional observations on a distinctive cutaneous myofibroblastic tumour with emphasis on differential diagnosis.

Br J Dermatol 1993 Jul;129(1):69-73

Department of Histopathology, St Thomas' Hospital (UMDS), London, U.K.

Following the very recent description of a benign plaque-like myofibroblastic tumour of the skin, known as dermatomyofibroma, we present four further cases, emphasizing its clinical features and its histological differential diagnosis. Three patients were adult females and one was a boy. Two of the lesions arose on the anterior abdominal wall, one on the shoulder, and one on the neck. Read More
