Mycosis fungoides presenting as reticular erythematous mucinosis.

Background: Mycosis fungoides has numerous clinical presentations.

Methods: We present two cases in which mycosis fungoides clinically mimicked reticular erythematous mucinosis.

Results: Both patients had extracutaneous involvement.

Tinea capitis mimicking dissecting cellulitis: a distinct variant.

Background: Tinea capitis is a common scalp dermatosis with several clinical patterns. Only two patients with a presentation of tinea capitis mimicking dissecting cellulitis have been described in the English literature.

Observation: We report a patient with tinea capitis mimicking dissecting cellulitis who did not respond to griseofulvin therapy at 16 mg/kg/day but eventually cleared after a protracted course of higher dose griseofulvin.

Cutaneous T-cell lymphoma sparing resolving dermatomal herpes zoster lesions: an unusual phenomenon and implications for pathophysiology.

Exclusion of cutaneous T-cell lymphoma (CTCL) by another dermatosis has not been reported. The mechanism for the epidermotropism of helper T lymphocytes in this indolent malignancy is not known. Although there is evidence that Langerhans cells (LC) play a role in the epidermotropism of lymphocytes in CTCL, clinical or in vivo support is lacking.
