We present the case of a 42-year-old Indian male with prurigo nodularis, exhibiting multiple verrucous, brownish-black nodules on the left lower and right upper extremities, with milder involvement of the right lower extremity. The lesions were asymmetrically distributed in a near-linear pattern, with prominent white hyperkeratosis and associated moderate pruritus and paresthesia. Differential diagnoses included pemphigoid nodularis, verruca vulgaris, and hypertrophic lichen planus, with a biopsy confirming prurigo nodularis.

The dermoscopic rainbow pattern (RP), also known as polychromatic pattern, is characterized by a multicolored appearance, resulting from the dispersion of polarized light as it penetrates various tissue components. Its separation into different wavelengths occurs according to the physics principles of scattering, absorption, and interference of light, creating the optical effect of RP. Even though the RP is regarded as a highly specific dermoscopic indicator of Kaposi's sarcoma, in the medical literature, it has also been documented as an atypical dermoscopic finding of other non-Kaposi skin entities.

Hypertrophic lichen planus (HLP) is an idiopathic inflammatory condition characterized by hyperkeratotic plaques or nodules, typically occurring bilaterally on the wrists, ankles, or lower extremities. This variant of lichen planus is more common among African-American patients and occupies a broad differential with other keratotic skin conditions, some of which are malignant, making recognition and accurate diagnosis essential. We present an unusual case of a 49-year-old African-American woman with four markedly exophytic, horn-like lesions on her shins, ultimately diagnosed as HLP.

Article Synopsis
  • A cross-sectional study was conducted in Pakistan to analyze the clinical characteristics of Childhood Lichen Planus (LP) in patients under 15 years of age at a Tertiary Care Hospital from December 2021 to December 2023.
  • The study found that the average age of onset was approximately 9.8 years, with 94.4% of patients experiencing pruritus; classic LP was the most common type identified.
  • The research concluded that childhood LP is rare, closely resembles adult LP, and shows no significant gender preference, with instances of nail and mucosal involvement being particularly uncommon.
