Introduction/Background: Anetoderma is a rare and benign skin disorder characterized by a loss of elastic tissue in the mid-dermis. Among the five main types, the secondary form typically develops in areas of damaged or pathological skin. Understanding the origin of the anetoderma is pivotal for accurate diagnosis and management, considering the impact on patient outcomes. Therefore, in our study, we describe a patient who presented to Hospital of the State University of Haiti with secondary anetoderma.
Case presentation: Here we present a case study of a 26-year-old male who presented to the dermatology department with a protruding oval mass located at the lateral third of the posterior right arm. The patient did not experience any associated symptoms such as pain, erythema, or tenderness. The mass evolved over 30 months following the resection by cautery of a molluscum contagiosum (Figure 1). After the wound had healed, he noticed a hyperchromic macule with a wrinkled center that evolved overtime, eventually taking on the appearance of a cystic mass (Figure 2) with wrinkling and a bulged-out appearance. Routine evaluations were normal. The mass was surgically resected, and the cutaneous specimen was sent to pathology. The skin fragment measured 2 x 1.9 x 1.5 cm with a raised flaccid area, and the average resection margin was 0.7 cm. Upon sectioning, the tissue appeared firm and whitish. The adipose fragment was irregular and measured 1 x 1 x 0.4 cm. Microscopically, sections of skin including the epidermis and dermis were observed. Fragments of adipose tissue from the subcutaneous tissue were also present. The epidermis appeared regular, and the dense underlying dermis showed a few vessels with a discrete lymphoplasmacytic infiltrate surrounding them.  The clinical and pathological findings allowed us to confirm the diagnosis of secondary anetoderma. No atypical changes were observed. Since the resection, the patient has shown improvement with the incision site now displaying a mild hypertrophic scar. Regular monitoring and appropriate scar management has ensured favorable recovery.
Conclusion: This case illustrates the classic presentation of secondary anetoderma. Based on the available information, it is recommended to consider the possibility of anetoderma in patients presenting with skin lesions following molluscum contagiosum or other skin disorders where the integrity of the underlying elastic tissue is compromised. Consultation with a dermatologist and additional investigations, such as skin biopsy, may be necessary to confirm the diagnosis.
