Case reportTwo cases of syringotropic cutaneous T-cell lymphoma and review of the literature
Section snippets
Case 1
A 65-year-old Caucasian woman was referred to our dermatology clinic with a 6-month history of hair loss and erythematous, pruritic lesions on her scalp, neck, abdomen, groin, and back, which had been previously diagnosed as granulomatous dermatitis. She had received treatment with topical corticosteroids with little improvement. The patient's medical history was significant for mitral valve prolapse, depression, and stasis dermatitis as a result of chronic lower extremity edema.

Discussion
Although SLHA and syringotropic CTCL were previously considered separate conditions, the current literature suggests that they are varying presentations of the same disease. A correlation between syringotropic CTCL and SLHA was originally proposed by Burg and Schmockel4 in 1992. SLHA shares many of the same histopathologic features of syringotropic CTCL, such as hyperplastic eccrine glands surrounded by a lymphocytic infiltrate, but without the presence of heavy infiltrate of atypical
Conclusion
Currently syringotropic CTCL is categorized by the WHO-EORTC as a subtype of folliculotropic MF1; however, emerging data suggest that this classification system may need to be revisited. Although there is some histologic overlap between these two variants with some cases of folliculotropic CTCL having involvement of the eccrine glands and vice versa, the cumulative data regarding differences in epidemiology, pathogenesis, and prognosis suggest that syringotropic CTCL may merit classification as

2014, Journal of the American Academy of DermatologyCitation Excerpt :Palmar and plantar involvement by STMF was not reported in the previous studies on STMF by Pileri et al,5 but has been described in case reports.10,17,18 This, along with the deep location of the infiltrate, may explain the low rates of complete responses associated with topical treatments in STMF observed in the current study and others.7,9,10,19 Ulceration, which is not a typical presentation of MF, occurred in 4 cases, and had been previously described in 4 additional case reports of STMF,20-23 which suggests that it could be more frequent in STMF than in classic MF.
