Reported is a case of a 62-year-old African American female who presented with an asymptomatic, progressive rash of the left underarm and abdomen with histologic features suggestive of granuloma annulare. Biopsies revealed an interstitial pattern of cells in the dermis with prominent small aggregates of atypical lymphocytes, a few atypical lymphocytes in the lower epidermis, and a mild increase in dermal mucin. Immunohistochemistry staining revealed the atypical lymphocytes to be positive for CD3 and CD8 and negative for CD4 and CD7, an aberrant immunoprofile. Mixed in the dermis with the atypical lymphoid cells were a few CD68 positive histiocytes and S100 protein positive dermal dendritic cells. T-cell receptor beta gene rearrangement studies showed nearly the same clonal peaks for TCRB rearrangement in two biopsy specimens from separate sites, all supporting a diagnosis of interstitial mycosis fungoides. The patient is undergoing treatment with full body narrowband UVB (nbUVB) phototherapy with notable improvement in skin discoloration and resolution of several abdominal lesions. A diagnosis of interstitial mycosis fungoides is challenging to make based on clinical features alone and is often clinically misdiagnosed. Awareness of histopathologic features is critical to make an accurate diagnosis and thus patient management.<\/jats:p>","DOI":"10.1155\/2022\/3506738","type":"journal-article","created":{"date-parts":[[2022,9,5]],"date-time":"2022-09-05T21:05:09Z","timestamp":1662411909000},"page":"1-5","source":"Crossref","is-referenced-by-count":2,"title":["Interstitial Mycosis Fungoides: An Unusual Mimic of Interstitial Granuloma Annulare Not to Miss"],"prefix":"10.1155","volume":"2022","author":[{"given":"Neha","family":"Singh","sequence":"first","affiliation":[{"name":"Virginia Tech Carilion School of Medicine, Roanoke, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4599-3117","authenticated-orcid":true,"given":"Kiley K.","family":"Fagan","sequence":"additional","affiliation":[{"name":"Section of Dermatology, Department of Internal Medicine, Virginia Tech Carilion School of Medicine, Roanoke, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6346-094X","authenticated-orcid":true,"given":"Douglas J.","family":"Grider","sequence":"additional","affiliation":[{"name":"Section of Dermatology, Department of Internal Medicine, Virginia Tech Carilion School of Medicine, Roanoke, VA, USA"},{"name":"Department of Basic Science Education, Virginia Tech Carilion School of Medicine, Roanoke, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0560.2002.290302.x"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/pas.0000000000000679"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346-8138.2012.01657.x"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2133.2002.47321.x"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1111\/cup.13707"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1001\/archdermatol.2008.46"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2013.03.036"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199407000-00001"},{"key":"9","first-page":"171","article-title":"What is the clue and what is the diagnosis?","volume":"3","author":"A.
