Pulmonary sarcoidosis presenting as a solitary nodule mimicking lung cancer

Sarcoidosis shows various clinical and radiologic manifestations. Nodular sarcoidosis is an uncommon form of pulmonary sarcoidosis. Cases presenting as solid nodules are especially rare. We herein present a case of nodular sarcoidosis with a solid nodule that was suspected to be lung cancer.

Manifestations of Besnier-Boeck-Schaumann sarcoidosis on skin

Besnier-Boeck-Schaumann sarcoidosis is a multisystemic disease of unknown etiology. Only about 25 % of patients have cutaneous involvement. Every patient with cutaneous sarcoidosis should be evaluated for possible systemic sarcoidosis. This article contains descriptions and original images of clinical forms of the disease: miliary sarcoidosis, circinate sarcoidosis, nodular sarcoidosis, angiolupoid (Brocq-Potrier), lupus pernio (Besnier-Tennesson), erythema nodosum, subcutaneous sarcoidosis (Darier-Roussy). Differential diagnosis and treatment of patients are discussed.

Nodular Sarcoidosis Masquerading as Cancer

Nodular lung disease is a rare pulmonary manifestation of sarcoidosis and resembles metastatic neoplasm disease. Nodular sarcoidosis is rare, varying from 1.6% to 4% of patients with sarcoidosis. Radiographic nodules measure from 1 to 5 cm in diameter that typically consist of coalescent granulomas. There is limited data on this form of sarcoidosis and its presentation can mimic primary or metastatic pulmonary neoplasms. Nodular sarcoidosis has a favorable prognosis, and resolution can be seen with oral corticosteroids. Herein, we present such a case of nodular pulmonary sarcoidosis with a lung nodule measured up to 6 cm.

Four Decades of Necrotizing Sarcoid Granulomatosis: What Do We Know Now?

Context In the 4 decades since Dr Averill A. Liebow introduced necrotizing sarcoid granulomatosis, there have been publications of numerous cases, but its nature and possible relationship to classical and nodular sarcoidosis have been and remain controversial. Liebow introduced necrotizing sarcoid granulomatosis as a provisional diagnostic term and stated that “the problem is whether the disease represents necrotizing angiitis with sarcoid reaction, or sarcoidosis with necrosis of the granulomas and of the vessels.” There has, as yet, been no definitive answer to the questions that he raised. Objective To determine whether there is a relationship between necrotizing sarcoid granulomatosis and nodular sarcoidosis in order to ascertain whether the current prevailing opinion that they are related is correct. Data Sources The world's literature on necrotizing sarcoid granulomatosis from 1973 to 2013 and nodular sarcoidosis from 1952 to 2013 was critically reviewed. One hundred three cases of necrotizing sarcoid granulomatosis and 111 cases of nodular sarcoidosis were found suitable for individual case analysis. Conclusion The data showed a striking overlap in the clinical, radiologic, and pathologic features of both entities, strongly supporting the conclusion that necrotizing sarcoid granulomatosis is a previously unrecognized manifestation of sarcoidosis and is essentially the same as nodular sarcoidosis. It is proposed that use of necrotizing sarcoid granulomatosis as a diagnostic term be discontinued and replaced by sarcoidosis with necrotizing sarcoid granulomatosis pattern provided that an infectious etiology can be reasonably excluded. Our concept of sarcoidosis should now be expanded to recognize that there is a continuous spectrum of necrosis ranging from minimal to extensive.
