Poroma: A Retrospective Series of 80 Patients at a Tertiary Care Hospital. / Poroma. Estudio retrospectivo de 80 pacientes en un hospital terciario.

BACKGROUND: Poroma is a benign, exclusively cutaneous, adnexal tumor with a predilection for palmoplantar skin. OBJECTIVE: To analyze the clinical characteristics of poroma in our population. MATERIAL AND METHODS: Retrospective study of patients diagnosed with poroma between 2002 and 2021. We conducted a chart review to record age; sex; number, location, and diameter of lesions; time since onset; clinical characteristics; suspected clinical diagnosis; resection margin status; recurrences; and follow-up duration. Categorical variables were compared using the Fisher exact test. Continuous variables were compared using the t test or the Mann-Whitney U test depending on whether they were normally or nonnormally distributed. RESULTS: We studied 80 patients (31 women and 49 men) with a median (interquartile range [IQR]) age of 65.5 (29) years. Median time since onset of poroma was 12 (21) months. Median lesion diameter was 8(7)mm, and none of the patients had multiple lesions. The lesions were located on the head and neck in 13 cases, the trunk in 13, the upper extremities in 11, and the lower extremities in 43. Twenty-three lesions (28.8%) were located at acral sites (5 on the palms and 18 on the soles). Women were more likely to have scalp lesions (P=.041). Acral lesions were more likely to be erythematous (P=.014). Five patients experienced local recurrence. CONCLUSIONS: Although poromas are particularly common in acral locations (especially the feet), most of the lesions in our series (71.3%) were located elsewhere. Acral lesions were more likely to show the classic clinical features of erythema and exophytic growth.

Prevalence of and risk factors for dermatoporosis: a prospective observational study of dermatology outpatients in a Finnish tertiary care hospital.

BACKGROUND: Dermatoporosis describes the cutaneous signs and complications related to chronic cutaneous fragility related to ageing, chronic sun exposure and long-term use of topical and systemic corticosteroids. Chronic renal failure may be an additional cofactor. The prevalence of dermatoporosis is estimated around 32-37% in France among the elderly. OBJECTIVE: We evaluated the prevalence of dermatoporosis and its risk factors in outpatients who attended a consultation in the department of dermatology of Helsinki University Central Hospital. METHODS: A prospective observational study of 176 consecutive outpatients aged 60 years and older, who attended a consultation in the department of dermatology of Helsinki University Central Hospital. Data collection included age, gender, reason for consultation, local or systemic corticosteroid therapy, antiplatelet drugs and anticoagulant therapy, diabetes and chronic kidney failure (glomerular filtration rate < 60 mL/min/m2 ). The presence of dermatoporosis, location on the body and staging were collected. RESULTS: 30.7% presented dermatoporosis. Lesions were mainly located on the upper limbs (94%), and stage I was the most frequent (75.9% of the cases). Multivariate analysis revealed that dermatoporosis was significantly associated with ultrapotent topical corticosteroids (odds ratio (OR) 5.34, 95% CI 1.85-15.43, P = 0.002), oral corticosteroids (OR 3.22, 95% CI 1.18-8.80, P = 0.022), concomitant corticosteroid therapy, anticoagulant and chronic renal failure (OR 4.02, 95% CI 1.34-12.01, P = 0.013) and age (OR 1.05, 95% CI 1.01-1.10, P = 0.016). Patients with bullous pemphigoid were those with the highest prevalence of dermatoporosis in our cohort (64%). CONCLUSION: Acknowledging the selection bias in our study, the prevalence of dermatoporosis in a dermatology consultation in Finland seems as frequent as in France. These results prompt us to weigh the indications of long-term corticosteroids use in frail elderly patients.
