RESUMEN
Recombinant interferon beta-1b is one of the treatment options of multiple sclerosis (MS). Insertional biologics that are used in the treatment of MS may lead to skin adverse effects, for example, morphea.
RESUMEN
The "chik sign" is considered to be one of the most common cutaneous features of chikungunya fever and has been considered unique to this disorder. It consists of brownish hyperpigmentation involving the nose. We report a case of a 3-year-old boy with dengue infection who presented with macular hyperpigmentation of nose simulating the chik sign. Hyperpigmentation is an unusual cutaneous manifestation in cases of dengue.

Granuloma multiforme (GM) is a chronic granulomatous skin condition which is clinically characterised by annular lesions mainly over sun-exposed areas and histologically by focal necrobiosis and histiocytic granulomas. Its significance lies in the fact that it can clinically resemble tuberculoid leprosy and hence it can be missed. Here, we report a case of GM from India in a 55-year-old female agriculturist, with multiple asymptomatic large annular rings of papules over the photo-distributed areas. Histopathology helps in confirming the diagnosis and in differentiating it from similar clinical and histologic mimics such as granuloma annulare, tuberculoid leprosy, interstitial granulomatous dermatitis or annular sarcoid. Though a high degree of suspicion is needed to diagnose GM, it should be considered as a differential for various annular conditions.
