Lichenoid granulomatous dermatitis: A case with dramatic desquamation and multiple potential causes.

Lichenoid granulomatous dermatitis, also known as giant cell lichenoid dermatitis, represents an uncommon mixed-pattern dermatitis with histopathologic features of interface dermatitis with band-like lymphocytic inflammation of the dermal-epidermal junction, with thinning of the epidermis or lichen planus-like changes, and granulomatous inflammation involving the dermis. Lichenoid granulomatous dermatitis can manifest with a variety of primary lesions and has various clinical associations. We present a challenging clinicopathologic case of lichenoid granulomatous dermatitis in a 58-year-old woman with dramatic cutaneous desquamation in the context of a complex medical history and multiple potential triggers.

Time course for recovery of peak aerobic power after blood donation.

Peak aerobic power (VO2peak) is decreased after blood donation, but the time course for full recovery is unknown. We measured VO2peak and exercise time to fatigue before and weekly for 4 weeks after 450-ml blood donation at a blood donor clinic, to determine the time course of recovery. Twelve moderately active individuals (2 women, 10 men; 24.
