(1) Background: Frontal fibrosing alopecia (FFA) is a scarring alopecia that predominantly affects postmenopausal women; (2) Methods: A retrospective, observational, single-center study was conducted in the Hospital General Universitario in Ciudad Real, Spain, including all patients diagnosed with FFA between 2010 and 2021; (3) Results: A total of 306 patients (296 women and 10 men) were included in our study. The mean age of onset was 59.5 years. The severity of this disease was evenly distributed between mild (147 patients) and severe (149 patients) forms. There was a positive, statistically significant, medium correlation between the severity of the disease and its time of progression. Moreover, hypothyroidism was present in 70 patients (22.9%) and classic signs of concomitant lichen planopilaris were observed in just 30 patients (9.8%), while other forms of lichen planus were uncommon. The estimated prevalence in our population is 0.15% and the incidence is 15.47 new cases per 100,000 inhabitants; (4) Conclusions: The time of progression was positively correlated with the severity of FFA. However, the presence of clinical signs, such as inflammatory trichoscopic signs, was not associated with the progression of this condition.
Acquired perforating dermatosis (APD) is a disorder of transepidermal elimination of keratin, collagen or elastic fibers. APD is mainly associated with diabetes mellitus and chronic kidney disease. We present the case of a 66‐year‐old male, poorly controlled diabetic with peripheral arterial disease, obesity, arterial hypertension, Cushing's syndrome and chronic kidney disease requiring hemodialysis who develops an acquired perforating dermatosis. Due to the patient's comorbidities, treatment with corticosteroids, cyclosporine and phototherapy is not possible. He does not respond to gabapentinoids or allopurinol. The outbreaks of skin lesions and pruritus were accentuated in situations of renal function deterioration; however, hemodialysis did not improve her dermatosis, causing a great deterioration of her quality of life. It was decided to start treatment with dupilumab with the dosage used in atopic dermatitis, achieving a complete response of both pruritus and skin lesions. With this case, we want to show how dupilumab can be an effective tool to treat acquired perforating dermatosis.
This case report describes an 83-year-old woman with a generalized pruritic eruption comprising annular and polycyclic plaques on the face, neck, trunk, and extremities with changing appearance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
