An unusual localization of lichen amyloidosus in a patient with IgG k benign monoclonal gammopathy is reported. After topical treatment with dimethylsulfoxide the lesions improved, but histological examination still showed amyloid deposits.
Successfully meeting a shared goal usually requires co-actors to adopt complementary roles. However, in many cases, who adopts what role is not explicitly predetermined, but instead emerges as a consequence of the differences in the individual abilities and constraints imposed upon each actor. Perhaps the most basic of roles are leader and follower. Here,… (More)
We report a rare heterozygous status for Fabry's gene with severe kidney involvement and normal alpha-galactosidase A activity, together with the intrafamilial variations in the clinical expression of the disease. The random X inactivation hypothesis seems to explain such a variable expression of the alpha-galactosidase gene in our cases.
Epithelial-myoepithelial carcinoma (EMC) is a rare tumor with predilection for the major salivary glands, mainly the parotid gland. It is a tumor of low grade malignancy, and despite its tendency to local recurrence with low metastatic potential, rare cases of EMC may have an aggressive behavior with distant metastasis. Treatment consists primarily of… (More)
Sporotrichosis is the most common deep mycosis in many tropical regions. The etiologic agent, Sporotrichum schenckii, is easily cultivated but rarely seen in histologic sections.
Radiotherapy is a treatment option for the majority of malignancies. However, because melanoma is known to be radioresistant, the use of ionizing radiation as an adjuvant therapy in cutaneous melanoma patients is ineffective. Obesity has now been recognized as a risk factor for melanoma. High adiposity is generally associated with a more pro-oxidative… (More)
Nuclear morphometric parameters and polarity of basal keratinocytes have been evaluated by computerized image analysis in solar keratoses, comparing the results with normal sun-exposed skin and squamous cell carcinoma 1st Broders degree. The cellular index demonstrated higher levels in all keratoses. The morphometric nuclear parameters revealed major values… (More)
The distribution of free SH groups and SS covalent linkages in hypertrophic, atrophic, acantholytic, bowenoid, pigmented solar keratoses (SK) and squamous cell carcinoma was evaluated. The sulphydryl groups were present in cytoplasms with a granular pattern and nucleoli mainly in atrophic, hypertrophic and bowenoid SK; the distribution of SS linkages… (More)
