Epidermal acanthosis, incipient, and completed acantholysis of many of the spinous keratinocytes of the epidermis and foci of dyskeratosis are well-recognized histologic findings. We have observed solitary lesions on the “scalp” of patients having a Hailey–Hailey–like pattern, and not the suprabasilar clefting of pemphigus represents the first manifestation of pemphigus vulgaris, which was confirmed with direct immunofluorescence in all our patients. *Zucker School of Medicine at Hofstra/Northwell, Lake Success, NY; and †Ackerman Academy of Dermatopathology, New York, NY.
