Malignant lymphoma has various pulmonary manifestations on chest CT, including nodules, masses, areas of consolidation, and ground-glass opacity. These presentations can pose a diagnostic challenge, as they mimic other disease patterns. Herein, we report a case of diffuse large B-cell lymphoma (DLBCL) manifesting as miliary nodules in a 67-year-old male initially presenting with dyspnea and fever. Radiologic findings included diffuse, bilateral, multiple tiny nodules consistent with metastasis, miliary tuberculosis, and fungal infection. However, further investigations, including laboratory tests, imaging, and biopsies, led to the diagnosis of DLBCL involving the lungs. Herein we reported a rare case of lymphoma involvement of the lung presenting as miliary nodules. Accurate diagnosis relies on a comprehensive evaluation of the clinical history, physical features, laboratory test results, and imaging findings.

Coccidioidomycosis is a rare systemic fungal infection in Korea. However, the incidence of coccidioidomycosis has recently begun to increase due to the increasing incidence of people traveling overseas to endemic areas. In previously reported cases of coccidioidomycosis in Korea, the radiographic findings usually showed a solitary pulmonary nodule, pleural effusion, cavitation, and hilar lymphadenopathy, but no miliary nodules. We report a case of disseminated coccidioidomycosis with miliary nodules in an immunocompetent patient. A 32 year old male, who had traveled in Corona, New Mexico, USA, was admitted for an evaluation of persistent cough with fever. Chest radiography revealed initially diffuse multiple small nodules that appeared to be miliary tuberculosis. However, a subsequent evaluation revealed that he had disseminated coccidioidomycosis.

Purpose: Sebaceous carcinoma is a rare malignant tumor derived from the adnexal epithelium of sebaceous glands. This tumor usually occurs on the eyelids, but uncommonly it may occur on the extraocular sites. It is characterized by a tendency of local recurrence and occasional metastasis. Surgical excision is appropriate treatment for patients with sebaceous carcinoma. Because this kind of case is rare, we report two cases of sebaceous carcinoma developed on scalp. Methods: Case 1 was a 69 - year - old woman. She visited the hospital with a $1.5{\times}2.5cm$ sized reddish yellow - colored, slowly growing mass on left parietal scalp. The mass began at birth and started growing at 5 years ago. Case 2 was a 67 - year - old woman. She had $2.5{\times}3.0cm$ sized yellow - colored mass on right parietal scalp. It occured at birth and started growing at 3 years ago. And the masses had erythematous ulcer with sanguineous discharge. In the beginning, the masses were miliary nodule. Results: CT scan and fine needle biopsy were done. Case 1 and 2 were diagnosed as sebaceous carcinoma. Wide excision with safety margin of 10 mm and split thickness skin graft was done. Histological examination revealed well demarcated, irregular, variable sized tumor lobules. Each lobule was composed of sebaceous and undifferentiated cells. Postoperatively, the patients did well and the lesion had not recurred. Conclusion: Sebaceous carcinoma is an aggressive malignant tumor. It often can be mistaken for other skin tumors. Authors experienced two rare cases of sebaceous carcinoma developed on scalp. We recommend early wide excision with enough safety margin as treatment of sebaceous carcinoma.
