HMB-45 does not react well against intradermal nevi, normal adult melanocytes, spindle cell melanomas and desmoplastic melanomas. HMB-45 is nonreactive with almost all non-melanoma human malignancies, with the exception of rare tumors showing evidence of melanogenesis (e.g., pigmented schwannoma , clear cell sarcoma ) or tumors associated with ...
Melanoma: CD79a: Primary cutaneous marginal zone lymphoma Primary cutaneous follicular lymphoma Diffuse large B-cell lymphoma leg type: CD117: Mast cell: Mastocytosis: CD138: Plasma cell: Multiple myeloma Plasmablastic lymphoma: CD207 (Langerin) Langerhans cell: Langerhans cell histiocytosis: Chloracetate esterase (Leder) Mast cell ...
Desmoplastic melanoma, also known as neurotropic melanoma, or spindled melanoma [1] is a rare cutaneous condition characterized by a deeply infiltrating type of melanoma [2]: 696 with an abundance of fibrous matrix. It usually occurs in the head and neck region of older people with sun-damaged skin.
A Spitz nevus is a benign skin lesion.A type of melanocytic nevus, it affects the epidermis and dermis. [1]It is also known as an epithelioid and spindle-cell nevus, [2] and misleadingly as a benign juvenile melanoma, [2]: 691 and Spitz's juvenile melanoma [3]).
Melanocytic tumors of uncertain malignant potential (MELTUMP) are melanocytic lesions in the dermis that cannot be classified by morphology as either benign naevi (moles) or malignant melanomas because the mass shows features of both.

A rhabdomyoblast is a cell type which is found in some rhabdomyosarcomas. [1] When found histologically, a rhabdomyoblast aids the diagnosis of embryonal, alveolar, spindle cell/sclerosing, and pleomorphic rhabdomyosarcomas; however, in a tumor, expression of the rhabdomyoblast phenotype is not the only factor in diagnosing a rhabdomyosarcoma.
Atypical fibroxanthoma (AFX) is frequently found to have a well-circumscribed, nonencapsulated dermal tumor that is either contiguous with the epidermis or separated from it by a narrow zone of collagen (Grenz zone); plump spindle cells with prominent nuclei, epithelioid cells, and multinucleated giant cells; atypical mitoses and severe ...
