Universal acquired melanosis is a rare cause of diffuse hyperpigmentation of skin and mucosa during childhood. There are only few reported case of this scarce syndrome in medical literature. We report the first case of universal acquires melanosis from Iran in a 4-year-old girl whose skin becomes darker after 2-month of age.

Figure 3 Atypical acquired melanosis, shown by clusters ofabnormal melanocytes in the epithelium, migrating awayfrom the basement membrane. Squamous metaplasia ofthe epithelium, with loss ofgoblet cells, is also seen. Haematoxylin and eosin. Magnifcation x300. We present an unusual case in which conjunctival melanoma was preceded by excision of a lentigo maligna melanoma ofthe ipsilateral lower...

We describe imaging findings in a 2-year-old girl with neurocutaneous melanosis and malignant cerebral melanoma. Because the cerebral melanoma in this child was of the amelanotic type, high-signal intensity on unenhanced T1-weighted images was not present. The cutaneous lesions played a crucial role in establishing a correct (presumed) histopathologic diagnosis on the basis of the imaging findi...

Effect of different concentrations hypotaurine (HTU) on melanosis and quality shrimps during 10 d storage in ice were studied. During refrigeration, the total plate count volatile basic nitrogen treated with 20 g/L HTU lowest, hardness microstructure best. Moreover, score melanoses, pH bile acid also low. Sensory evaluation showed that treatment could make shelf life 3-4 days longer compared co...

background although, melasma is most prevalent among asian young women, and also darkly pigmented individuals are particularly prone to developing post inflammatory hyperpigmentation, to the best of our knowledge, there are rare or no studies about the association of melasma and post inflammatory hyperpigmentation. results we found out that 24.1% of patients without melasma had post-acne pigmen...

Polyphenoloxidase (PPO), protease activities, melanosis and exudate loss of pre-cooked Pacific white shrimp (Litopenaeus vannamei) subjected to multiple freeze-thaw cycles (1, 3 and 5 cycles) using different thawing methods were studied. PPO and protease activities increased as freeze-thaw cycles increased (p < 0.05). Thawing using running tap water resulted in the higher increases in both PPO ...

Melanosis coli denotes brownish discoloration of the colonic mucosa found on endoscopy or histopathologic examination. The condition has no specific symptom on its own. It is a fairly frequent incidental finding of colonic biopsies and resection specimens. The pigmentation is caused by apoptotic cells which are ingested by macrophages and subsequently transported into the lamina propria, where ...
