In which condition can a chronic eruption of waxy, papules lead to coalescence into a ring?

• A. Psoriasis
• B. Granuloma annulare
• C. Seborrheic keratosis
• D. Contact dermatitis

Answer: (B)

Granuloma annulare is characterized by a chronic skin condition presenting with waxy papules that can coalesce to form ring-like lesions. This condition typically manifests as smooth, skin-colored or slightly erythematous bumps that may expand outward to create a ring, resembling annular patterns. The etiology of granuloma annulare is not entirely understood, but it is often associated with underlying systemic conditions or can occur idiopathically. In contrast, psoriasis is associated with silvery scales and plaques but does not typically form ring-like structures. Seborrheic keratosis presents as raised, wart-like lesions that may appear smooth or scaly but lacks the ring formation characteristic of granuloma annulare. Contact dermatitis results from an allergic reaction or irritant exposure and typically presents with redness, itching, and varying degrees of inflammation, rather than the distinct rings associated with granuloma annulare. Thus, the specific features of granuloma annulare make it the condition that aligns with the described clinical presentation of waxy papules leading to coalescence into a ring.
