The optical properties of coatings pigmented with different black colorants were systematically investigated and their surface temperatures and cooling energy savings were estimated. The black coatings pigmented with chromite iron nickel black and manganese ferrite black spinel colorants are not cool enough to be energy efficient cool black coatings. The cool black coatings pigmented with NIR-t...

Here we have studied the population of intrinsically photosensitive retinal ganglion cells (ipRGCs) in adult pigmented and albino mice. Our data show that although pigmented (C57Bl/6) and albino (Swiss) mice have a similar total number of ipRGCs, their distribution is slightly different: while in pigmented mice ipRGCs are more abundant in the temporal retina, in albinos the ipRGCs are more abun...

An 87-year-old woman with a history of multiple basal cell carcinomas presented to a follow-up visit referring a pigmented, slowly growing lesion on her right scapula that had been present for one year. Physical examination revealed an irregular 12 x 5 mm well circumscribed pigmented lesion with an elevated keratotic surface (Figure 1). The dermoscopic evaluation revealed a multicomponent patte...

Pigmented villonodular synovitis (PVNS) is a rare benign neoplastic proliferation of synovial tissue which is typically localised and usually responds well to surgery and/or radiotherapy. We present a case of unusually aggressive of PVNS of the hip in a 73-year-old woman.

Epidermal nevi are cutaneous hamartomas developing from ectoderm and one of their types is verrucous epidermal nevus. During the neonatal period, they are pink or slightly pigmented and velvety. Later, they darken and the surface become more warty. When lesions are distributed on one side of body, it is termed nevus unis lateralis. Lymphangioma is a lymphatic malformation which manifests with f...

Primary pigmented tumors of the cerebrospinal meninges are rare and uncommon group of melanin-containing neoplasms. They include pigmented meningioma, malignant melanoma, meningeal melanocytoma, melanotic schwannoma and melanoblastosis. These tumors are different in biological behavior, treatment and prognosis. Valenti was the first to describe pigmented cells normally found in the leptomeninge...

A 32-year-old man presented with a floater in his right eye of 1-day duration. Examination revealed visual acuity 20/20 2 disc-diameter, pigmented, translucent, freely floating, oval cystic lesion the midvitreous (Fig A, inset showing magnified view). Ultrasonography highlighted nature an anechoic center and hyperechoic borders B) OCT well-defined hyperreflective structure hyporeflective lumen ...

Background: Pigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a m...

Five pigmented isolates of Mycobacterium avium subsp. paratuberculosis were examined by pulsed-field gel electrophoresis (PFGE), IS900 restriction fragment length polymorphism (IS900-RFLP), and IS1311 polymorphism analysis using PCR. All of the pigmented isolates exhibited one of three distinct PFGE profiles with SnaBI, designated 9, 10, and 11, and with SpeI, designated 7, 8, and 9, which gene...

Cellular blue nevus is an uncommon pigmented tumor in the conjunctiva, where it generally appears as a deep, circumscribed, pigmented conjunctival mass. We report a case of conjunctival blue nevus that clinically resembled primary acquired melanosis and gave rise to conjunctival melanoma. A 41-year-old man developed a diffuse pigmented mass in the inferior fornix of his left eye. Over a 20-year...
