Healing rate is the most accurate method to predict healing; however, there are no data in atypical ulcers. We retrospectively analyzed clinical features, associated comorbidities, and therapies of 159 patients with atypical ulcers. In a subgroup of 59 patients, we analyzed the areas, perimeters, and the healing rate (mm/d) as prognostic indicators of wound healing. Atypical ulcers were more frequent among women (n = 98) with an average age of 76 years. Confirmed by biopsy, the etiologies were as follows: inflammatory diseases (38%), neoplastic ulcers (29%), vasculitis (21%), drug-induced ulcers (7%), and infectious ulcers (4%). Systemic therapies were applied based on the different etiologies. Wound bed preparation principles guided the local treatment. The average reduction of the area during the observation interval was 36%, while the average reduction in the perimeter was 41%. Overall, 51 ulcers showed a reduction in wound size and 8 ulcers showed an increase. Neoplastic ulcers were the group with the fastest healing rate, with an average speed of 0.24 mm/d. The slowest healing occurred in the inflammatory group with an average healing rate of 0.032 mm/d. The initial area and perimeters influenced wound healing; however, ulcer etiology and comorbidities significantly altered the healing rate.
