We report the clinicopathological features of an agminated clear cell tumor, arising in a 67-year-old man, otherwise asymptomatic, with distinct histopathological and immunohistochemical features, which did not fit into any existing diagnostic categories. The patient presented with several skin-colored papules at the lateral and posterior aspects of the neck, which on histopathological examination showed circumscribed lobular aggregates of clear cells within the dermis. The immunohistochemical marker panel performed showed diffuse expression of vimentin, NKI-C3, and CD64 while revealing marked negativity for factor XIIIa, CD10, CD13, CD14, CD34, CD68, CD163, lysozyme, HMB45, Renal Cell Carcinoma antigen, calponin, h-caldesmon, Anti-alpha smooth muscle actin antibody [1 A4], S100, and pancytokeratin, leading the authors to postulate a monocytic origin.<\/jats:p>","DOI":"10.1097\/dad.0000000000000709","type":"journal-article","created":{"date-parts":[[2016,11,8]],"date-time":"2016-11-08T13:06:12Z","timestamp":1478610372000},"page":"212-216","source":"Crossref","is-referenced-by-count":2,"title":["Agminated Clear Cell Tumor: An Impostor of PEComa and Distinctive Dermal Clear Cell Mesenchymal Neoplasm"],"prefix":"10.1097","volume":"39","author":[{"given":"Ana Isabel","family":"Teixeira","sequence":"first","affiliation":[{"name":"Servi\u00e7o de Dermatovenereologia do Centro Hospitalar de Lisboa Norte, Lisboa, Portugal; and"}]},{"given":"Lu\u00eds","family":"Soares-Almeida","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Dermatovenereologia do Centro Hospitalar de Lisboa Norte, Lisboa, Portugal; and"}]},{"given":"Heinz","family":"Kutzner","sequence":"additional","affiliation":[{"name":"Dermatopathologische Gemeinschaftspraxis, Friedrichshafen, Germany."}]}],"member":"276","reference":[{"key":"R1-20230908","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1097\/DAD.0b013e3182106d28","article-title":"Cutaneous clear cell neoplasms: a histopathological reappraisal","volume":"34","author":"Biswas","year":"2012","journal-title":"Am J Dermatopathol."},{"key":"R2-20230908","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1111\/cup.12240","article-title":"Eruptive dermal clear cell desmo-plastic mesenchymal tumors with perivascular myoid differentiation in a young boy.
