Organizing pneumonia associated with multicentric reticulohistiocytosis

Organizing pneumonia (OP) is a clinicopathological entity that occurs idiopathically or in association with several conditions such as connective tissue diseases. Multicentric reticulohistiocytosis (MRH) is a systemic disease characterized by polyarthritis and mucocutaneous lesions, but lung involvement is uncommon. We report a patient with MRH associated with OP. This case may be of interest w...

Solitary Type of Congenital Self-healing Reticulohistiocytosis

Congenital self-healing reticulohistiocytosis is a rare, congenital, benign, self-healing variant of Langerhans cell histiocytosis. It usually appears as multiple papules or nodules; however, occurrence of the solitary type is very rare. We report on a case of solitary congenital self-healing reticulohistiocytosis in a 29-day-old girl who presented with a papule on her sole. Two months later, t...

Multicentric Reticulohistiocytosis with Dermatomyositis-like Eruptions

A 68-year-old man presented with polyarthritis, proximal muscle weakness, and erythema of the face, arms, neck, and anterior chest that resembled the V-neck sign. Initially, dermatomyositis (DM) was considered because of the erythema, polyarthritis, and muscle weakness. He also had mediastinal and hilar lymphadenopathy on contrast-enhanced computed tomography. Unexpectedly, a biopsy of the fore...
