Sequential development of dermatofibrosarcoma protuberans in the forehead and eyelid
Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous sarcoma that constitutes 1% of all soft tissue sarcomas and <0.1% of all malignancies.1,2 The distinguishing features are slow growth, local aggressiveness, low metastatic potential, and elevated rates of local recurrences.1,2 The tumour occurs on the trunk, particularly on the chest and shoulders, in 40%–50% of cases; on the proximal parts of the limbs in 30%–40% of cases; and on the scalp, cheeks, and supraclavicular area in 10%–15% of patients.Malignant transformation of retinocytoma treated with intra-arterial chemotherapy
Clara Knieper was most likely the first to make the closest description of what is currently known as retinocytoma, in a child named Peter Neuburger, born on May 12, 1899, and who underwent bilateral enucleations 11 years apart.1 Since then, the clinical features of this rare tumour have become well established and include a translucent greyish retinal mass sometimes associated with a staphyloma, calcific foci, retinal pigment epithelial alterations, cystic areas, and chorioretinal atrophy without exudation and prominent feeder vessels.Bilateral conjunctival Splendore-Hoeppli phenomenon associated with juvenile xanthogranuloma
The Splendore-Hoeppli phenomenon is considered a rare and distinct local mucocutaneous inflammatory reaction to antigens of a vast variety of infectious agents including fungi, bacteria, and parasites, and to some foreign material such as silk sutures.1 Hypereosinophilic syndrome and allergic conjunctival granulomas are noninfectious disorders that may also be associated with Splendore-Hoeppli phenomenon.1,2 In most conjunctival lesions, however, the definitive causative agent cannot be identified.
