A Rare Case of Solitary Hemorrhagic Mycosis Fungoides With Angiocentric Features

CD8+ mycosis fungoides with ichthyosiform clinical presentation and angiocentric feature

Mycosis fungoides (MF) is characterized by epidermotropic atypical lymphocytes infiltrate with α/β T-helper memory immunophenotype (βF1+, CD3+, CD4+, CD45Ro+, and CD8-). Angiocentricity is always associated with aggressive behavior or poor outcome in primary or secondary cutaneous lymphomas. Rare cases of angiocentric MF with a T-cytotoxic immunophenotype (CD3+, CD4-, CD8+, TIA-1+) have been described. Here, we report a 27-year-old man diagnosed with MF, clinically presenting with ichthyosiform lesions on his trunk and limbs. Biopsy demonstrated a CD3+ and CD8+ atypical lymphocytic infiltrate with marked epidermotropism and angiocentricity. Awareness of this rare MF variant with unusual clinicopathological characteristics is important to avoid misdiagnosis.

Unilesional mycosis fungoides: a case report and review of literature

Mycosis fungoides (MF) is the commonest primary cutaneous T-cell lymphoma (CTCL). Classically MF is presented clinically as multilesional disease but occurrence of solitary lesion, though quite rare, is on the record. This rare variant of MF is clinically and histopathologically indistinguishable from classic MF. Due to the rarity of the presentation the clinician may miss the diagnosis and the pathologist may also be in diagnostic dilemma specially if not clinically oriented. Here we describe a case of unilesional/solitary MF (UMF) in a 59 years old male who was initially clinically diagnosed as inflammatory dermatosis and was treated accordingly without any appreciable clinical response for over 4 years. Unresponsiveness to empirical treatment led to biopsy which finally proved it to be UMF. The clinical, light microscopic and immunohistochemical features of UMF are briefly reviewed to create awareness among the clinicians and pathologists about this rare variant of MF.
