Bullous solar elastosis.

Solar elastosis is a recognized manifestation of chronic sun exposure affecting mainly Caucasian skin. Recognizable clinical manifestations of solar elastosis include cutis rhomboidalis nuchae, Favre-Racouchot syndrome, actinic comedonal plaque, nodular forms such as elastomas, elastic nodule of the ear and elastotic bands, collagenous plaques of the hand, and colloid milia. We report two patients with an unusual presentation of vesicular lesions clinically and histopathologically situated in zones of severe solar elastosis that has been previously referred to as bullous solar elastosis.

Angiolymphoid hyperplasia with eosinophilia associated to a squamous cell carcinoma of the ear.

BACKGROUND: Angiolymphoid hyperplasia with eosinophilia is a benign vascular proliferation that usually affects the head and neck region. METHOD: An 89-year-old man who had a squamous cell carcinoma on the posterior aspect of one ear developed lesions of angiolymphoid hyperplasia with eosinophilia on the anterior aspect of the same ear. RESULTS: After surgical treatment of the malignant neoplasm, the lesions of angiolymphoid hyperplasia with eosinophilia disappeared spontaneously. CONCLUSIONS: Damage to the vasculature of the ear by the malignant neoplasm or the release of angiogenic factors by the same neoplasm is a plausible explanation for the development and eventual resolution of the vascular proliferation.

Granular parakeratosis.

This is a report of a 60 year-old black female patient presenting with pruritic brownish crusted plaques on both axillae of one month evolution. Histopathology revealed findings characteristic of axillary granular parakeratosis. This entity was first described by Northcutt et al in 1991. Since then, involvement of other intertriginous areas have also been reported. A review of the literature was performed and the term granular parakeratosis is suggested to emphasize its pathognomonic histopathologic features.
