Syringotropic mycosis fungoides (STMF) is a very rare variant of cutaneous T-cell lymphoma. It follows a much milder disease course than its clinically indistinguishable adnexal counterpart, folliculotropic mycosis fungoides (FMF). We report a case of a 36-year-old man who presented with erythematous, studded papules and plaques on the left upper extremity and right anterior thigh diagnosed as mycosis fungoides (MF) Stage 1A on initial superficial shave biopsy.

The presence of a granulomatous reaction in cutaneous lymphomas has been described in the past, especially in mycosis fungoides (MF), where a "granulomatous" variant of the disease is well known. We describe a patient with granulomatous MF (GMF) who has been followed for 13 years presenting with erythematosquamous plaques on his fingers and toes, ankles, heels, and abdomen, which on microscopic examination showed a lichenoid granulomatous reaction admixed with a neoplastic proliferation of small-sized, atypical CD4 lymphocytes. GMF is characterized by a granulomatous reaction intermingled with the dermal infiltrate of MF which may even reach the subcutaneous tissue. Read More

In this study, we used matrix-assisted laser desorption/ionization-Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR-MS) to perform lipidomic profiling of 5 MF tissue samples and 44 serum samples (22 from MF patients and 22 from control subjects). Multivariate statistical analysis of the mass spectral data showed that MF tissues had altered levels of seven lipids and MF sera had altered levels of twelve. Read More

Folliculotropic mycosis fungoides (FMF), a variant of mycosis fungoides (MF) with distinct clinical features, is characterized by infiltration of malignant T cells in hair follicles. This raises the hypothesis that antigens in the hair follicle may contribute to the pathogenesis of FMF. T-cell receptor β gene (TRB) sequences as well as dendritic cell subsets in patients with FMF (n = 21) and control patients with MF (n = 20) were studied to explore this hypothesis.
