Phacomatosis pigmentokeratotica (PPK) is a rare syndrome defined by the association of an organoid nevus occasionally with sebaceous differentiation, a speckled lentiginous nevus, and other extracutaneous anomalies. A preterm male infant of only 830 g at 27 week gestational age had an organoid nevus showing sebaceous differentiation. Also, he had multiple speckled-lentiginous nevus. Correlating...

An 18 year old girl concurrently developed skin lesions of morphoea (localised scleroderma) and pain and swelling of the hands and fingers. There were no dermatological or systemic signs of systemic sclerosis. The immunological features (high titred speckled antinuclear antibody, negative DNA binding, high titred positive anti-RNP and negative anti-Sm antibodies, speckled nuclear Ig fluorescenc...

We propose a fly-eye-like imaging system for seeing objects embedded in scattering media. Objects are recovered from many speckled images observed by a digital camera through a microlens array. Each microlens in the array generates a speckle image of the object buried between two layers of chicken breast tissue. In the computer each image is Fourier transformed jointly with an image of the spec...

Sir, The association of a speckled lentiginous naevus, an organoid naevus with sebaceous differentiation and skeletal and neurological anomalies, constitutes a specific syndrome that has been called phacomatosis pigmentokeratotica (1). It has been hypothesized that the co-occurrence of the two different naevi reflects a so-called twin spot phenomenon (1 – 3). We herein describe an additional ca...

A 7-year-old Caucasian female resident of the southern coast of Brazil presented dark spots on the left palm that converged to a unique macule with speckled pattern at about 1 month. The mycological exam and the fungi culture were typical of Hortaea werneckii, the agent of the superficial mycosis Tinea nigra. The patient received butenafine hydrochloride 1% for 30 days, resulting in a complete ...
