ABSTRACT

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. Immunohistochemical study combined with confocal microscopy revealed co-expression of CD4 and CD8 in a subset of atypical T lymphocytes. To our knowledge, this is the second report of a CD4/CD8 dual-positive MF.

ABSTRACT

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. Although clinically thought to be a malignant melanoma, histopathological, dermoscopic and reflectance confocal-microscopy examinations did not confirm this diagnosis.

ABSTRACT

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. These may occur in areas of subepidermal bullous eruption. We report an original case of bullous PLE complicated by milia. Such association has not been reported previously.

ABSTRACT

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. This is the first case described of this clinical presentation with a L2b genovar strain, occurring immediately after use of a sex toy. It suggests that this presentation is favoured by host immunity and behavioural factors. These factors may also play a part in the new outbreak of LGV.

ABSTRACT

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. This type of observation is rarely reported in the medical literature.

ABSTRACT

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. IgM-fluorescent treponemal antibody test and typical serologic parameters promptly led to the diagnosis of secondary syphilis. We initiated an appropriate antibiotic therapy using benzathine penicillin, which induced healing of the tongue lesions. The differential diagnosis of this lesion may include oral squamous carcinoma, leukoplakia, candidosis, lichen planus, and, especially, hairy oral leukoplakia. This case report emphasizes the importance of considering secondary syphilis in the differential diagnosis of hairy oral leukoplakia. Depending on the clinical picture, the possibility of syphilis should not be overlooked in the differential diagnosis of many diseases of the oral mucosa.
