Total Hemi-overgrowth in Pigmentary Mosaicism of the (Hypomelanosis of) Ito Type: Eight Case Reports.
2016
Abstract Pigmentary mosaicism of the (hypomelanosis of) Ito type is an umbrella term, which includes phenotypes characterized by mosaic hypopigmentation in the form of streaks, whorls, patchy, or more bizarre skin configurations (running along the lines of Blaschko): these cutaneous patterns can manifest as an isolated skin disorder (pigmentary mosaicism of the Ito type) or as a complex malformation syndrome in association with extracutaneous anomalies (most often of the musculoskeletal and/or nervous systems) (hypomelanosis of Ito). Affected individuals are anecdotally reported to have also partial or total body hemi-overgrowth (HOG), which often causes moderate to severe complications. We…

Amelanotic conjunctival melanoma
2006
Conjunctival melanoma is a rare condition of the eye pigment predominantly affecting white adults. We describe a 32-year-old white man with an amelanotic malignant melanoma of the conjunctiva that is not associated with primary acquired melanosis (PAM) or melanocytic nevus. The patient presented with a 2-year history of nonpigmented vascularized nodules of the right eye. Results of hematoxylin and eosin (H and E) staining of the lesion showed an invasive nodule with vertical spreading, invasion of the substantia propria corneae, and ulceration. S100 protein was expressed in the cells of the invasive nodule. HMB45 protein was highly positive in the melanoma cells. The de novo amelanotic mali…
Über das Vorkommen von „Hämatoxylin-Körpern” bei einem Naevuszellnaevus und einer Melanosis Dubreuilh
1966
Typischen „Hamatoxylin-Korperchen” (Gross), wie sie als Suchzeichen zur autoptischen Erfassung eines Lupus erythematodes bekannt sind, im HE-Schnitt auserst ahnliche, wenn nicht gar identische „Karyolyten” werden im Epidermis-nahen Cutisbereich eines Naevuszellnaevus vom Compound-Typ sowie einer Melanosis praeblastomatosa circumscripta Dubreuilh beschrieben. Die Genese derartiger Gebilde (physiko-chemische Zustandsanderungen in Nahe der Basalzell-Linie vielleicht infolge Durchtrankung mit Blutplasmaeiweisstoffen von antinuclearem Charakter) wird erortert. Dabei wird die Frage, ob dem Vorkommen solcher „Hamatoxylin-Korperchen”, wie sie vorangehend auch schon bei anderen Krankheitszustanden a…

THE MARKET FOR ALTERNATIVE SPECIES OF SHRIMP (PARAPENEUS LONGIROSTRIS) MINIMALLY PROCESSED TO INCREAS THE SHELF LIFE
2012
A reason that has put at the center of attention the crustaceans has been the growing demand for fast food products to which these fishes are particularly suitable. This paper proposes for the first time the use of the species of shrimp Parapeneus longirostris of the Mediterranean sea to realize precooked trays of V range and analyze the evolution of the process of melanosis with respect to commercial products in general coming from the Atlantic Ocean.
Clinicopathological and Immunohistochemical Study of Oral Amalgam Pigmentation
2012
Amalgam tattoo, the most common exogenous oral pigmentation, can sometimes be confused with melanotic lesions, being then biopsied. We present the clinicopathological characteristics of 6 biopsied cases (5 females and 1 male) of oral amalgam pigmentation. The most common location was the gingival mucosa, followed by the buccal and palatal mucosa. Morphology and distribution (stromal, perivascular, perineural, endomysial) of pigmentation was variable; there was only 1 case with fibrous capsular reaction and likewise only a single case of granulomatous foreign body reaction. Morphological variability is conditioned by the timing and amount of the pigment deposit, which is often associated wit…

Oral lesions and immune status of HIV infected adults from eastern Nepal
2013
Objective: To document the prevalence, age and gender distribution of oral lesions in HIV infected adults and the influence of highly active antiretroviral therapy and correlate them to the immune status of the patients. Materials and Methods: Oral lesions were diagnosed by a detailed physical examination by trained and calibrated examiners according to the case definitions established by the Oral HIV/AIDS research alliance. Demographic details, risk behavior patterns and oral symptoms and habits were collected by a questionnaire. Results: 81 patients; 54 men and 27 women aged between 20 ' 55 years participated in the study. A total of 49 patients; 60.5% had some oral lesion when examined. …
