Cosmetic Talc-Related Pulmonary Granulomatosis

Pulmonary talcosis in the setting of cosmetic talcum powder use

Pulmonary talcosis is a rare pneumoconiosis that is difficult to diagnose and may progress to debilitating lung disease. Four types of talcosis are described in literature: talc-silicosis and talc-asbestosis secondary to inhalation in industry workers and talc-emboli in intravenous drug users that self-inject talc-containing oral tablets. Although found in common household products, talc is overlooked as a cause of pneumoconiosis. Talcosis caused by cosmetic face powder is even rarer. Here we discuss a woman in her 50s who developed talcosis from inhalation of cutaneous cosmetics two years prior, and how comprehensive history may be crucial in diagnosing this rare disease.

Challenging Mimickers in the Diagnosis of Sarcoidosis: A Case Study

Sarcoidosis is a systemic granulomatous disease of unknown cause characterized by a wide variety of presentations. Its diagnosis is based on three major criteria: a clinical presentation compatible with sarcoidosis, the presence of non-necrotizing granulomatous inflammation in one or more tissue samples, and the exclusion of alternative causes of granulomatous disease. Many conditions may mimic a sarcoid-like granulomatous reaction. These conditions include infections, neoplasms, immunodeficiencies, and drug-induced diseases. Moreover, patients with sarcoidosis are at risk of developing opportunistic infections or lymphoma. Reliably confirming the diagnosis of sarcoidosis and better identifying new events are major clinical problems in daily practice. To address such issues, we present seven emblematic cases, seen in our department, over a ten-year period along with a literature review about case reports of conditions misdiagnosed as sarcoidosis.
