Mycosis fungoides (MF) is defined as an epidermotropic primary cutaneous T-cell lymphoma composed of small-to-medium-sized T lymphocytes with cerebriform nuclei and with a T-helper phenotype. LeBoit first described an unusual variant of MF with dermal acid mucin deposition. Such a variant was still considered in the list of clinicopathological variants of MF by Cerroni and colleagues. We herein report a case of patch-stage MF with abundant papillary dermal mucin deposition in a clinical setting of an erythematous patch on the lower abdomen and thigh.

Atypical Variant

Acquired ichthyosis is a known paraneoplastic sign of lymphoproliferative malignancies, with histopathologic findings that are nonspecific, revealing no insinuation of the underlying neoplasm. Mycosis fungoides (MF) is a skin malignancy of T helper lymphocytes with a wide clinical spectrum. Among the atypical variants of MF, there is an ichthyosis- like presentation. However, to date, rare cases of ichthyosiform MF has been reported. We report here the clinical and histopathological features of patient with IMF.

The Face

Mycosis fungoides is represented as the most common epidermotropic cutaneous T-cell lymphoma, which is mainly characterized by the proliferation of atypical cells within the epidermis. We report a rare presentation of mycosis fungoides in a 60-year-old male presenting with chronic psoriasiform plaque involving the face. Punch biopsy of the lesion from the forehead was taken for routine histological examination and immunohistochemical stains. Results of biopsy and immunohistochemical findings were consistent with mycosis fungoides and diagnosed as psoriasiform presentation of mycosis fungoides involving the face.

Although most patients with the cutaneous T-cell lymphoma, mycosis fungoides (MF), are seronegative for human T-cell lymphotropic virus-I or -II (HTLV-I/II) when tested by assays that measure only antibodies to the viral structural proteins, the majority of such patients harbor HTLV-I-related pol and tax proviral sequences that encode proteins not included in routinely used serologic tests. Tax mRNA has also been detected in their peripheral blood mononuclear cells (PBMC). Therefore, it seemed possible that these patients have antibodies to the tax protein. To investigate this, enzyme-linked immunosorbent assays (ELI-SAs) and Western blot assays were set up, using as antigens the full-length HTLV-I tax cloned from the prototypic HTLV-I-infected cell line, C91PL, and from PBMC of a MF patient, as well as a synthetic peptide made to the carboxy-terminal 20 amino acids of tax-I. Of 60 MF patients whose PBMC were shown to be positive for tax proviral DNA and mRNA, 50 (83%) were shown to have tax antibodies. The antigen derived from the MF patient was most useful in detecting such antibodies. These results demonstrate the need for including other HTLV-related antigens in addition to gag and env in serologic tests used to identify HTLV-infected individuals. The findings underscore the fact that individuals considered seronegative on the basis of currently used tests can be infected with HTLV.
