Double-positive CD4/CD8 mycosis fungoides: a rarely reported immunohistochemical profile.

Mycosis fungoides (MF) represents the most common epidermotropic cutaneous T-cell lymphoma (CTCL), and tumor cells typically express a mature T-helper memory phenotype. A minority of MF patients display an unusual phenotype, which may be either CD4(-)/CD8(+) or double negative. Herein, we report a case of biopsy-proven MF in a 31-year-old woman who presented with infiltrated plaques involving photoprotected areas of the skin.

Photoletter to the editor: Blue nevus with satellitosis mimicking melanoma. Contribution of dermoscopy and reflectance confocal microscopy.

Blue nevus is an acquired benign melanocytic nevus that can undergo malignant transformation. We report a 70-year-old man who presented with a recently enlarged long-term blue nodule on his scalp. He reported onset of new satellitosis around the lesion.

Milia complicating bullous polymorphic light eruption.

Polymorphic light eruption (PLE) is the most common photosensitivity disorder. Typically, PLE manifests in the spring or summer months as a recurrent pruritic papular and/or vesicular eruption occurring on photoexposed skin areas following sun exposure. The milia are caused by proliferative tendencies of the epithelium after injury.

First case of "bubonulus" in L2 lymphogranuloma venerum.

Since 2003, an ongoing lymphogranuloma venereum (LGV) proctitis outbreak has been reported in industrialised countries with a new variant designated L2b. Only men who have sex with men (MSM) are affected and most are HIV co-infected; delayed or incorrect diagnoses are frequent. We report a rare clinical case of LGV primary stage called "bubonulus" with penile adenopathy and secondary local acute lymphoedema in an MSM seropositive man.

Rapid onset of acute carcinoma of the glans penis arising three years after a lichen sclerosus.

Lichen sclerosus and atrophicus (LSA) is an inflammatory disease of incompletely characterised pathogenesis. If the development of squamous cell carcinoma (SCC) during the evolution of LSA is well described in women, this complication is a matter of discussion in men. We report an unusual case of acute and aggressive SCC which complicated the evolution of an LSA of the glans penis within three years.

Secondary syphilis simulating oral hairy leukoplakia.

We describe a case of secondary syphilis of the tongue in which the main clinical presentation of the disease was similar to oral hairy leukoplakia. In a man who was HIV seronegative, the first symptom was a dryness of the throat followed by a feeling of foreign body in the tongue. Lesions were painful without cutaneous manifestations of secondary syphilis.
