A 60-year-old female patient, asymptomatic and previously healthy. The patient have presented for 12 years cutaneous papules and erythematous-violet nodules. The lesions appeared in overlapping outbreaks, ulcerated, and resolved spontaneously, leaving residual atrophic scars. Affected areas included the trunk, buttocks, thighs, legs, arms, and forearms (Figure 1). The patient had already been submitted to four biopsies with inconclusive diagnoses. The patient showed good general condition through physical examination, without lymphadenopathy or hepatosplenomegaly. The biopsy of an infiltrated non-ulcerated papule revealed hyperkeratosis, rectification of the epidermis, and dense V-shaped infiltrate in the dermis, consisted of round cells with conspicuous cytoplasm and large pleomorphic vesicular nuclei, sometimes bevelled, displaying coarse nucleoli (Figure 2). Some binucleate cells resembling Reed-Sternberg cells, and numerous mitotic figures were observed. No intermingled neutrophils or eosinophils were identified. Immunohistochemistry showed positive reactions of neoplastic cells for anti-CD45LCA and anti-CD30, and negative for anti-CD3, anti-CD4, anti-CD8, and anti-CD20. After the final diagnosis of LP type C, treatment with UVB phototherapy was initiated.
