RESUMEN
Pigmented purpuric dermatoses (PPD) are a group of diseases characterized by petechiae and bronze discoloration of the skin on the lower extremities. Histopathologically, superficial perivascular lymphocytic infiltration and hemosiderin deposition are seen. PPD can be subdivided into progressive pigmentary dermatosis of Schamberg, purpura annularis telangiectoides of Majocchi, pigmented purpuric dermatitis of Gougerot and Blum, eczematid-like purpura of Doucas and Kapetanakis, itching purpura, and lichen aureus. The granulomatous variant of PPD was described in 1996. Granulomatous PPD share common histopathologic features of PPD with granulomatous inflammation. We present the findings of a patient who presented with a clinical picture of PPD and histologic patterns of granulomatous inflammation.

RESUMEN
Erythema elevatum diutinum (EED) is a rare, chronic inflammatory skin disease of unknown etiology. Clinical findings involve symmetrical livid-erythematous to red-brown papules and plaques or nodules. The skin lesions are located over extensor surfaces and often over joints. Histological findings are characterized by leukocytoclastic vasculitis and dense neutrophilic infiltration in the early stages of the lesions and by fibrosis in the late stages. EED may be associated with several hematological disorders, infectious diseases, immunological disorders, and certain malignancies. We report on a 59-year-old man with EED associated with multiple myeloma.

Extravasation of contrast media into subcutaneous tissue is a relatively frequent complication. Although most patients complain of initial swelling, tightness, and burning pain at the site of extravasation, some experience little or no discomfort. In most cases, conservative management is recommended. However, severe injury after extravasation of contrast media have been reported, including skin ulceration, tissue necrosis, and compartment syndrome, in which cases surgical intervention should be considered. We report a case of a 53-year-old man who had severe localized reaction due to extravasation of contrast media for a follow-up brain CT scan after subarachnoid hemorrhage.

Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory condition of unknown etiology. It occurs in young, parous women who had experienced breast feeding, and is manifested as a tender breast mass. Histologically, a discrete granulomatous lobulitis consisting of giant cells, neutrophils, epitheloid cells, and foamy macrophges is shown. Extramammary manifestations of IGM are rare. Erythema nodosum (EN), arthralgia, and episcleritis have been reported, supporting the theory that there is an autoimmune component in the etiology of IGM. Coincidence of IGM and EN is rare. Herein, we report a 28-year-old pregnant woman in whom granulomatous mastitis presented with arthralgia and EN.
