Desmoplastic Melanoma

Clinics in Laboratory Medicine, 2009
Desmoplastic melanoma (DM) is a variant of spindle cell melanoma characterized by the presence of abundant fibrous matrix. It is typically found in the head and neck region on chronically sun-damaged skin of older individuals. Early detection is uncommon, because its clinical features are not distinctive. DM is prone to misdiagnosis not only clinically

Desmoplastic Melanomar

Annals of Otology, Rhinology & Laryngology, 1994
Desmoplastic melanoma is an uncommon type of malignant melanoma that has a predilection for the skin of the head and neck. Because of a progressive metaplasia of melanocytes and an accompanying desmoplasia, the neoplasm can be mistaken for benign or malignant soft tissue lesions.

Desmoplastic trichoepithelioma

Cancer, 1977
Fifty examples of a distinctive clinicopathologic entity occurred in 49 patients who ranged in age from 8 to 70 (median 46) years. Forty-nine tumors were on the face, mainly the cheek, chin and forehead; most were present one to five years, and 85% of the patients were female.

Pathology of the Desmoplastic Ameloblastoma

Journal of Oral Pathology and Medicine, 2001
Abstract: Desmoplastic ameloblastoma is a rare variant of ameloblastoma and only 54 cases have been previously reported in the English literature. We report ten cases of desmoplastic ameloblastoma of the jaw observed between 1972 and 1998 and discuss the pathogenesis of the tumor.

Desmoplastic and non‐desmoplastic ameloblastoma: a comparative clinicopathological analysis

Oral Diseases, 1996
OBJECTIVES: The aim of this study was to review a large series of ameloblastomas, accessioned during a period of 35 years in a single Oral Pathology Diagnostic Center, for the incidence of desmoplastic ameloblastoma (DA) and in order to analyze the clinical features of this unusual variant.MATERIALS AND METHODS: All cases diagnosed as ameloblastoma ...

Desmoplastic Leiomyosarcoma of the Skin

The American Journal of Dermatopathology, 2000
This report focuses on two unusual cases of cutaneous leiomyosarcoma composed of sparse numbers of neoplastic cells embedded in abundant sclerotic stroma throughout the entire neoplasm. To the best of our knowledge, only one example of this rare lesion has been described previously as "sclerotic primary cutaneous leiomyosarcoma." However, the ...

Recurrent desmoplastic fibroma

International Journal of Oral Surgery, 1976
Two cases of recurrent desmoplastic fibroma are reported and the relevant literature reviewed. In both cases the original lesion was incompletely removed more than 10 years previously and the slow but aggressive spread of the recurrences is documented.

Desmoplastic Seborrheic Keratosis

The American Journal of Dermatopathology, 2003
Eleven cases of seborrheic keratoses with desmoplastic stroma and associated nests and cords of squamous epithelium simulating infiltrating carcinoma are presented. There were 7 males and 4 females ranging in age from 44 to 88 years (mean = 62). Eight cases were on the head and neck, one each on the lower and upper extremity, and one on the pubic area.

Desmoplastic Nevus Versus Desmoplastic Melanoma

2014
Among the melanocytic lesions with most difficult differential diagnosis we should include those with spindle and fibrous stroma (i.e., desmoplastic features). This is true not only because both benign and malignant melanocytic lesions may show these morphologic features (desmoplastic nevus and desmoplastic melanoma), but also since other, non ...

Desmoplastic neurotropic melanoma

Seminars in Cutaneous Medicine and Surgery, 1997
Desmoplastic neurotropic melanoma (DNM) is a rare variant of a spindle cell melanoma. The majority of these tumors occur on the head and neck of elderly patients. The rather variable clinical appearance (e.g. frequent lack of pigmentation) makes initial diagnosis often difficult. Histologically, DNM may show a lentiginous melanocytic proliferation with
