Case ReportsSarcoidosis presenting with a granulomatous reaction confined to red tattoos.
A patient with sarcoidosis who presented with a granulomatous tattoo reaction is described. Although tattoo granulomata usually represent a local hypersensitivity reaction to tattoo pigments, they can be a manifestation of systemic sarcoidosis. In this case the lesions were confined to the red areas of tattoos suggesting that tattoo sarcoid may be more than just an example of the Koebner response.

Case ReportsThe development of scar sarcoidosis at the site of desensitization injections.
Tender nodules may develop at the site of injection of allergen extracts. Some cases can be related to the aluminium contained in the preparation. ⋯ At presentation, there were no other cutaneous signs of sarcoidosis; systemic signs only developed 2 years later. We suggest that sarcoidosis be considered as a cause of granulomata developing at sites of desensitizing injections, particularly when aluminium is not involved.

Chromonychia induced by antineoplastic agents has been known for several years. The most frequent of these is melanonychia, either diffuse or in tranverse or longitudinal bands, that may co-exist with diffuse pigmentation of the skin. Although any cytostatic agent may be involved in melanonychia, this condition appears most commonly after treatment with adriamycin and cyclophosphamide or in polychemotherapy. Leukonychia, either true or apparent, seems to be less frequent and is the reason for our reporting two patients with this colour change.

Case ReportsSystemic sclerosis sine scleroderma presenting with vitiligo-like depigmentation and interstitial pulmonary fibrosis.
We report a case of systemic sclerosis sine scleroderma in which vitiligo-like depigmentation and early interstitial pulmonary fibrosis predominated. The pigmentary changes occurring in systemic sclerosis are reviewed and the distinctive features of the case discussed.
