Erythroderma as a manifestation of leprosy.

Erythroderma consists of erythema and scaling involving most or all of the body surface. This generalized eruption may be idiopathic, drug-induced or secondary to cutaneous or systemic disease. A 71-year-old man is reported presenting generalized erythema and desquamation with deck-chair sign, nail dystrophy, and plantar ulcers associated with loss of local tactile sensitivity.

Syndrome in question.

Morbihan Syndrome is a rare entity with unknown etiology. It is clinically characterized by chronic erythematous edema on the face - especially in the middle and upper third of the face - and creates abnormal facial contours that are initially intermitent but become permanent with the development of the syndrome. The histopathology is nonspecific and its therapy is a major challenge due to poor response to the various treatment options.

Cutaneous tuberculosis with nonreactive PPD skin test: a diagnostic challenge.

The authors report a case of cutaneous tuberculosis in a 63-year-old female patient, who had an infiltrated, erythematous-ferruginous plaque of indurated aspect on her right leg and a nonreactive PPD skin test. Diagnosis was made by tissue culture and PCR of skin biopsy material. The treatment was performed with pyrazinamide, rifampicin, isoniazid and ethambutol, with good response.

Case for diagnosis.

Intravascular papillary endothelial hyperplasia is a benign vascular lesion caused by proliferation of endothelium. It is reactive to thrombotic or inflammatory stimuli in the vessel wall.We report the case of a 14-yearold male patient with a violet-colored erythematous tumoral lesion of progressive growth in the occipital region.

Case for diagnosis. Localized scleroderma or morphea.

Localized scleroderma or morphea is a chronic disease of the connective tissue. Its etiology may be autoimmune and the condition results from a disturbance in collagen synthesis and deposition, clinically represented by sclerotic skin lesions. Some plaques may be yellowish, which can be misleading at diagnosis.
