Cutaneous Manifestations of Respiratory Diseases

Background: Cutaneous manifestations often accompany respiratory diseases, reflecting systemic involvement. These skin signs can provide vital clues for early diagnosis and management of pulmonary disorders. Objective: This study aims to evaluate the prevalence and nature of cutaneous manifestations in patients with respiratory diseases at Hamdard Institute of Medical Sciences and Research, India. Method: A cross-sectional study was conducted from April 2023 to August 2024, involving 110 patients diagnosed with various respiratory diseases. Detailed dermatological examinations were performed, and findings were correlated with clinical, radiological, and histopathological data. Statistical analysis was conducted to determine the relationship between cutaneous manifestations and respiratory diseases. Result: Out of 110 patients, 45% presented with cutaneous manifestations. The most common skin presentations included eczema (25%), erythema nodosum (10%), and digital clubbing (5%). Among patients with chronic obstructive pulmonary disease (COPD), 40% had associated skin conditions. In patients with sarcoidosis, 60% exhibited cutaneous signs, primarily erythema nodosum. In lung cancer patients, paraneoplastic skin conditions, including dermatomyositis, were seen in 15%. A significant correlation was found between the severity of respiratory diseases and the extent of skin involvement (p < 0.05). Early recognition of these dermatologic findings aided in timely diagnosis and improved clinical outcomes. Conclusion: Cutaneous manifestations are frequent in respiratory diseases, offering critical diagnostic and prognostic value. Clinicians should integrate dermatologic evaluations into routine respiratory disease management to enhance patient care.
