ABSTRACT
Follicular bronchiolitis (FB) is an uncommon pulmonary lymphoproliferative disorder that is characterized by the presence of peribronchiolar hyperplastic lymphoid follicles with reactive germinal centers. FB could be associated with systemic illnesses including immunodeficiency, infection, and autoimmune diseases. In Korea, a single case of FB with rheumatoid arthritis was recently described but there has been no report on FB associated with other rheumatic diseases. Herein, we describe the first case of FB presenting nodular ground-glass opacities (GGO), which mimicked lung cancer, in patients with primary Sjögren's syndrome (SS). The differential diagnosis of nodular GGO lesions should include FB although it is a rare manifestation in SS patients.

Mycobacterium avium complex (MAC) is an opportunistic bacterium that primarily infects acquired immune deficiency syndrome (AIDS) patients with low CD4+ T cell counts; however, peritonitis caused by MAC in AIDS patients is rare. Here, we report the first case of peritonitis caused by MAC in AIDS patients in Korea. A 41-year-old female with poor adherence to antiretroviral therapy was admitted to hospital with nonspecific symptoms; an abdominal computed tomography (CT) scan revealed substantial ascites, splenomegaly, and lymphadenopathy. Based on the CT scan and ascitic fluid cultures, MAC peritonitis was diagnosed. In addition to antiretroviral therapy, clarithromycin, rifabutin, and ethambutol were administered to treat the MAC infection, and the patient's symptoms improved.

BACKGROUND: Epoxy resin compounds are one of the common causes of occupational allergic contact dermatitis. In Korea, most cases of allergic contact dermatitis from epoxy resin compounds have been caused by the epoxy resin itself. We report a rare case of allergic contact dermatitis which was caused by epichlorohydrin, an ingredient of epoxy resin and 2,4,6-tris-(dimethylaminomethyl)phenol (tris-DMP), a kind of hardeners. CASE REPORT: A 43-year-old man, who had worked at the epoxy resin glue manufacturing factory since 1999, presented with mild and intermittent erythematous papules and rashes on his face, neck, trunk, and both arms. He was dealing with epoxy resin, epichlorohydrin, bisphenol A and hardeners. After a new hardener was added in August 2008, his skin lesions worsened from what he had experienced in the past. A skin patch test was performed to identify the causative chemicals of the skin lesion. Epichlorohydrin and tris-DMP elicited positive reactions after 48 hours and increased after 96 hours. CONCLUSION: This case confirmed occupational allergic contact dermatitis caused by epichlorohydrin and tris-DMP, an ingredient of epoxy resin and a hardener, respectively.
