Secondary Anetoderma Overlying Multiple Pilomatrixomas: A Case Report

Pilomatrixoma is a benign skin tumour originating from hair matrix cells. It usually presents as a solitary nodule or cyst. Multiple lesions are rare and are familial in majority of cases. Anetodermic changes overlying pilomatrixomas have rarely been described. We report here an 18-year old girl with six pilomatrixomas. None of her family members had similar lesions. Three of the lesions which were located on the back and arm showed features of secondary anetoderma

Unilateral Nevoid Telangiectasis: Report of Five Cases

Unilateral nevoid telangiectasia (UNT) is a rare cutaneous disorder characterized by superficial telangiectasias distributed unilaterally. UNT can be congenital or acquired. Acquired UNT may be seen during pregnancy, puberty, and in association with cirrhosis and hepatitis C. Besides, the disease has been reported in healthy individuals. In the etiology, elevated blood estrogen levels and/or increased estrogen and progesterone receptors in the involved skin are suggested to cause this disorder. Here, we present four male patients aged 26-33 years, without an identified underlying disease and an 18-year-old female hepatitis B carrier with diagnosis of acquired UNT. Since UNT is seen rarely, it is discussed in the light of the literature data

Impression Cytology in Different Types of Contact Lens Users

This study compared tear function tests and cytologic changes on the conjunctival surface in asymptomatic patients wearing contact lens of different materials. Included in this study were 40 eyes wearing daily wear 4 week replacement hydrogel (H) lenses, 32 eyes wearing silicone hydrogel (SiH) lenses, 18 eyes wearing rigid gas-permeable (RGP) lenses, and 21 healthy eyes (no lenses) as the control group. Epithelial morphology of the conjunctival surface was evaluated, based on Nelson classification with conjunctival impression cytology (CIC), after the tear break-up time (TBUT) and Schirmer test were performed. The mean values of the Schirmer and TBUT tests were significantly higher in the control group than in the other lens groups (p < 0.001). Grade 0 was the most frequent CIC in the control group (66.7%) and least frequent in the SiH lens group (40.6%); grade I was least frequent in the control and RGP groups (33.3%) and most frequent in the SiH lens group (40.6%). Moreover, grade 2 was most frequent in the SiH lens group (18.8%). There was no statistically significant difference in goblet cell densities between the groups (p = 0.462). In addition to the different Schirmer and TBUT test results between contact lens wearers and healthy non-wearers, some cytologic changes may occur on the ocular surface with direct mechanical effects of contact lenses. This simple and noninvasive technique may be used to evaluate the ocular surface with regard to intolerance to contact lenses

Histopathologic Approach to Oral Cavity Lesions

Diseases of the oral cavity may be either a reflection of system or cutaneous diseases or can be seen as a primary oral lesion. These lesions are inflammatory reactions due to miscellaneous mechanisms, ulceration or erosion, reactive proliferative nodules, precancerous or neoplastic diseases. In this study, microscopic features of the most common diseases, together with their differential diagnosis are discussed. Some of the diseases of the oral cavity have overlapping histopathological findings. In these conditions, ancillary methods such as immunoflourescence or immunohistochemistry can be performed. Deep biopsies from representative areas are essential for proper histopathological diagnosis. Moreover, informing the pathologist about the exact anatomic localization of the biopsy, as well as the clinical findings of the lesion is crucial for a better approach.

Generalized linear porokeratosis

A 23-year-old woman was seen for widespread skin lesions present since the age of 2.5 years. Twenty years ago, she developed a brown macular lesion on her right buttock. The lesion became hyperkeratotic and subsequently spread through the posterior aspect of her right leg. It later spread to the right side of the trunk and to the right arm. When she was 9 years old, she developed similar lesions on her left arm and leg. After she was 13 years old, no new skin lesions appeared. There was no family history of similar lesions
