The correct answer is B. CTCL.

This is actinic reticuloid which is typically in old men with eczematous erythematous plaques that become lichenoid in sun exposed areas. Histologically it looks like CTCL, however there are increased CD8 cells not increased CD4 cells like in CTCL.

Chronic actinic dermatitis is a rare skin condition that mainly affects men over the age of 50 years. It is characterized by severely itchy, red, inflamed, and thickened dry skin, mainly in areas that have been exposed to sunlight or artificial light. The condition is also known as chronic photosensitivity dermatitis and actinic reticuloid (this name comes from the histological findings of skin biopsies which resemble a reticulosis or  cutaneous T cell lymphoma)
