Less than 50 FRPC patients have been reported in the literature. Due to the limited number of cases, the pathophysiology of this unique entity remains elusive; moreover, no standard treatment has been agreed upon. Here, we report a case of FRPC in a 20-year-old male who was presented with generalized multiple discrete papules covered with central keratotic plugs in all regions of his body, particularly in the facial area, neck, abdominal, and extensor region of the extremities for more than 7 years. Similar symptoms were acknowledged in the patient’s family members. Histopathological analyses identified the crateriform shape invagination in the epidermis filled with inflammatory lymphocytes and basophilic debris and perforated by basophilic collagen bundles from the underlying dermis. Based on the clinical and histopathological findings, the patient was diagnosed with FRPC. He was treated with topical desoximetasone 0.25% cream applied 2– 3 times daily. A follow-up evaluation after 4 weeks revealed a near-complete resolution of skin papules. To our knowledge, this is the first report of FRPC case from Indonesia. Unlike the majority of FRPC patients who had their disease onsets during infancy or early childhood, FRPC skin manifestations in our patient started during the adolescence period. The resolution of skin manifestations after daily application of topical desoximetasone suggests that topical corticosteroids are a potential treatment option for FRPC patients.Keywords: familial reactive perforating collagenosis, benign dermatosis, central keratotic plug, crateriform shape invagination, topical desoximetasone
