Primary cutaneous follicle center lymphoma -'crosti lymphoma': what can we learn?

In 1951, Crosti reported on seven patients with 'reticulo-histiocytoma of the back' who presented with figurate erythematous plaques and nodules on the back or lateral trunk. Reticulo-histiocytoma of the back was later classified as a primary cutaneous follicle center lymphoma (PCFCL). A definitive diagnosis of the condition is frequently delayed because of a relative lack of clinical symptoms and difficulties in interpretation of the histologic findings.

Erythema multiforme-like drug eruption with oral involvement after intake of leflunomide.

Leflunomide is an antirheumatic agent of the type of a 'disease-modifying antirheumatic drug'. In rare cases, severe skin reactions up to the extreme expression of toxic epidermal necrolysis have been observed.

Diagnostic odyssey of a cutaneous mycobacteriosis rare in central Europe.

Cutaneous infection with Mycobacterium chelonae is an uncommon disease, although this atypical mycobacterium is an acid-fast bacillus ubiquitous in the environment. It is often misdiagnosed and treated as a fungal or common bacterial infection. We report a case of disseminated atypical mycobacterial skin infection of a 72-year-old woman who was treated with different topical and systemic antimycotic and antibiotic drugs over a period of 5 months without remarkable improvement.
