Introduction: Itching nodules and papules are common findings. A rare but important differential diagnosis is the nodular subtype of bullous pemphigoid. Methods and Results: The investigators report a female patient presenting with strongly itching papules disseminated over her extremities and trunk. Physical examination revealed multiple erythematous, mostly excoriated papules and nodules on her back, abdomen, and extremities. Histology showed changes compatible with prurigo lesion, and immunofluorescence showed positive results for BP180 and BP230. Considering these clinical, histologic, and immunofluorescence findings, the diagnosis of a nodular subtype of bullous pemphigoid was made. The patient showed healing of lesions under a combination therapy with systemic psoralen and ultraviolet A, topical application of corticosteroids, and systemic therapy with azathioprine and prednisolone. Discussion: Pemphigoid nodularis represents the rare prurigo variant of bullous pemphigoid. Typically, lesions show the same immunopathologic and histologic features as in common bullous pemphigoid but mostly without the characteristic clinical finding of bullae.

Ultraviolet radiation (UVR) from all three waveband regions of the UV spectrum, UVA (320-400 nm), UVB (290-320 nm), and UVC (200-290 nm), can be emitted by some medical devices and consumer products. Sunlamps can expose the blood to a considerable amount of UVR, particularly UVA and/or UVB. The percent transmission of each waveband through the epidermis to the dermis, which contains blood, increases in the order of increasing wavelength: UVC (10%) < UVB (20%) < UVA (30%). To investigate the effects of UVR on white blood cells, we chose transmission electron microscopy to examine the ultrastructure changes in L5178Y-R murine lymphoma cells.
