A 64-year-old man was referred with a 3-month history of 2 contiguous subcutaneous, non-in ̄ammatory painless nodules on the back of his right elbow (Fig. 1). His health was good on admission. The skin in this area was thin, fragile and atrophic, with numerous ecchymotic lesions. Cutaneous biopsy of 1 nodule showed a granulomatous dermal in®ltrate with giant cells. Periodic AcidSchiff staining r...

Sarcoidosis is an antigen-mediated disease of unknown aetiology, characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs. Cutaneous involvement in sarcoidosis is classified as specific, when biopsy reveals non-caseating granulomas, and non-specific, typically erythema nodosum. Granulomatous skin lesions occur in 9% to 37% of patients. The skin is the second...

The diagnosis of cutaneous sarcoidosis relies mainly on the patient's history, presence of characteristic skin lesions and histological examination that shows a granulomatous, non-necrotizing dermal infiltration. The aim of the study was to assess the ultrasonographic features of cutaneous lesions of sarcoidosis before and after treatment. A 38-year-old woman with systemic sarcoidosis and speci...

BACKGROUND Sarcoidosis is a multisystemic granulomatous disease of unknown origin. Chronic cutaneous lupus erythematosus (CCLE) is an autoimmune disease that is associated with autoantibody production and T-cell dysfunction. Cutaneous manifestations of sarcoidosis may mimic CCLE and vice versa making it difficult to reach a diagnosis clinically. CASE PRESENTATION We present a case of a 57-yea...

The presence of granulomas in the skin of T-cell lymphoma patients is a rare but well-known phenomenon. The authors present the case of a 44-year-old Caucasian male, with a previously treated peripheral T-cell lymphoma, with cutaneous infiltration and extensive dyschromia on his lower limbs. Skin biopsies revealed the presence of sarcoid granulomas associated with the recurrence of the lymphoma...

INTRODUCTION Cutaneous infection is an uncommon presentation of mucormycosis, usually seen after trauma, at the site of surgical drains or after occlusive dressings. The involved area is erythematous and painful, with varying degree of central necrosis. We report the case of chronic coetaneous infection of one year duration and without apparent necrosis in an immunocompetant patient. CASE PRE...

CASE REPORT A 3-year-old male neutered Domestic Shorthair cat was evaluated for a skin mass of approximately 2 × 3 cm arising from the right dorsolateral aspect of the tail at the junction between the proximal and middle one-thirds of the tail length. Incisional biopsy sample was consistent with granulomatous inflammation. The granuloma was surgically excised with 5 mm margins of normal skin. T...

conclusions alternariasis or similar cases may be increased due to the increased number of immunosuppressed patients. from this point of view, skin lesions in these patients must be planned and microbiologically evaluated considering the molds. case presentation we reported a case of wound infection induced by alternaria spp. in a renal transplant patients. the main interest in this case was th...

: Facial ulcers may be the manifestation of a wide variety disorders with infective, inflammatory, granulomatous, or malignant etiopathogenesis, leading to challenges in differential diagnosis and management. Mucormycosis is an angio-invasive, rapidly spreading, potentially fatal fungal infection beginning from nose paranasal sinuses after inhalation spores, manifesting cutaneous necrotic escha...

Twenty-one cases of pythiosis in horses (n = 10), dogs (n = 9) and cattle (n = 2) were investigated. The aetiology in all cases was confirmed by immunohistochemistry. Data related to the clinical course and outcome and localization of the lesions were obtained from pathology reports. The equine lesions consisted of fibrotic tissue with multiple, often coalescing, areas of immature granulation t...
