EPONYMS IN THE DERMATOLOGY LITERATURE LINKED TO THE SKIN AND SOFT TISSUE TUMORS

The term “eponym” originates from the Greek word “eponymous”, which means “named after”. An eponym was a simple way to describe tumors and tumor like lesions that initially were not well understood [1]. Most of the tumors in the skin and soft tissues are named according to its histopathological features under the microscope. Nevertheless, few of them are named eponymously. With the exception of Evans tumor which is currently best known as Low-Grade Fibromyxoid Sarcoma, the eponyms linked to the tumors in the skin and soft tissue maintain their position in the medical literature over the years. In this communication which is based, essentially [1], we aimed to highlight on selected eponyms in dermatology literature linked to the skin and soft tissue tumors, which we listed it in in Table I [1-10].

Bednar tumor
It is a name given to the pigmented type of Dermatofibrosarcoma protuberans (DFSP).DFSP is a locally aggressive soft tissue neoplasm with intermediate-to low-grade malignancy.Bednar tumor is named after a well-known Czech pathologist, Blahoslav Bednar (1916-1998) (Fig. 1).

Ewing sarcoma
Ewing sarcoma is a malignant osseous neoplasm that affects mostly children and young adult males.It was initially described as "endothelioma of bone" by James Ewing (1866-1943) (Fig. 3), in 1921.Ewing became the first professor of pathology at Cornell University, Weill Cornell Medical College.He was recognized as a central figure in emerging tumor pathology at that time and was dubbed "Cancer Man".
Clinically, the neoplasm presents with oedema, swelling, and pain of the involved area.
Histopathologically, Ewing's sarcoma consists of solid sheets of small round cells, with vesicular nuclei and scant cytoplasm, arranged in irregular masses separated by strands of fibrous tissue, with areas of necrosis en masse intermingled with intratumoural haemorrhage.Cutaneous metastases from Ewing's sarcoma are very uncommon.While, primary cutaneous Ewing sarcoma very rarely occurs and the prognosis has been reported to be better in some small series.

Kaposi sarcoma
It is a mesenchymal tumor that involves blood and lymphatic vessels and that affects multiple organs, most commonly the skin.It was first described as "idiopathic multiple pigmented sarcoma" by Moritz Kaposi Kohn (1837-1902) (Fig. 4), in 1872.Kaposi was born in Hungary, and graduated in medicine from the University of Vienna.He was one of the first to establish dermatology based on anatomic pathology.His book, Pathology and Therapy of the Skin Diseases in Lectures for Practical Physicians and Students, became one of the most significant books in the history of dermatology and was translated into several languages.

Maffucci syndrome
It is characterized by multiple enchondromas and soft-tissue hemangiomas, less commonly lymphangiomas, affecting the skin and musculoskeletal system.It is named after, an Italian pathologist, Angelo Maria Maffucci (1845-1903) (Fig. 5), who described it for the first time in 1881.He made also important scientific contribution in the field of tuberculosis.When multiple enchondromas, is not associated with hemangiomas, it is called Ollier disease, after a French doctor, Louis Xavier Édouard Léopold Ollier (1830-1900) (Fig. 6), who reported it, in 1898.Ollier is recognized for his contributions in orthopedic and reconstructive surgery.

Morton neuroma
It consists of perineural fibrosis and nerve degeneration of the interdigital nerve at the level of the metatarsal heads.It is not a true neuroma and is caused by compression and irritation of the nerve beneath the intermetatarsal ligament.
