Among the most common forms are superficial spreading melanoma, nodular melanoma, acral lentiginous melanoma, desmoplastic melanoma, and lentigo maligna melanoma. Some of the rarer forms, which fall into the category of miscellaneous melanomas, are melanomas with rosettes, angiotropic melanoma, animal-type melanoma, myxoid melanoma, chondroid melanoma, osteogenic melanoma, rhabdoid melanoma, follicular melanoma, nevoid melanoma, and angiomatoid melanoma. Angiomatoid melanoma was first described in metaplastic melanomas with clusters of neoplastic cells reminiscent of vascular channels. Immunohistochemically, this variant of melanoma is negative for vascular markers and positive for melanocytic markers. The angiomatoid pattern has been described in just 4 cases of melanoma to date in the English literature. The differential diagnosis is with angiosarcoma and pseudovascular squamous cell carcinoma.<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">1</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">We describe a case of primary angiomatoid melanoma on the right thigh of a 59-year-old man, with no evidence of metastasis at the time of diagnosis.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0030">Case Description</span><p id="par0015" class="elsevierStylePara elsevierViewall">We present the case of a 59-year-old man with a skin lesion on his right thigh. The patient reported that the lesion had been present for several months, but he did not specify the exact time. The clinical diagnosis was “probable hemangioma” and the lesion was completely excised. Histologic examination showed a nodular neoplastic lesion with infiltrating margins in the epidermis, extending into the reticular dermis. The neoplastic cells were medium to large in size and had pronounced pleomorphism, with several cells with irregular nuclei, granular chromatin, prominent nucleoli, and abundant cytoplasm interspersed with smaller cells with hyperchromatic nuclei and amphophilic cytoplasm (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Also identified was dispersed melanic pigment that was positive with Fontana-Masson stain. There were 2 mitoses in 10 high-power fields (×<span class="elsevierStyleHsp" style=""></span>40). The most striking finding was the presence of large channels with a cavernous vascular appearance filled with erythrocytes and surrounded by neoplastic cells (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Immunohistochemical staining of the neoplastic cells was positive for S-100 protein, HMB-45, and MiTF-1, and uniformly negative for CD31 (<a class="elsevierStyleCrossRefs" href="#fig0010">Figs. 2 and 3</a>). The cells were also positive for D2-40 (podoplanin) and negative for keratin AE1 and AE3 and p63. The Ki-67 proliferation index was 5% to 10%. Based on the above findings, a diagnosis of angiomatoid nodular melanoma was established, with a Clark level of IV, a Breslow thickness of 1.35<span class="elsevierStyleHsp" style=""></span>mm, absence of vertical growth phase, a moderate lymphocytic infiltrate at the base, no evidence of vascular or perineural invasion, or microsatellitosis, and tumor-free lateral and deep margins.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><elsevierMultimedia ident="fig0015"></elsevierMultimedia></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0035">Comment</span><p id="par0020" class="elsevierStylePara elsevierViewall">Alder et al.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">2</span></a> published the first description of angiomatoid melanoma in 1997.
