CASE REPORT Pigmented conjunctival lesions are a diagnostic challenge for the clinician. A 37-year-old man presented with a pigmented mass involving the conjunctiva of his right eye. Clinically, a diagnosis of malignant melanoma was made and a wide excision of the tumor was performed. The histopathologic diagnosis was seborrheic keratosis. DISCUSSION Seborrheic keratosis is a benign lesion wh...
Bowens' disease (BD) is a precancerous condition of skin and/or mucosa with a predilection towards sun-exposed areas. Extensive literature research failed to reveal any case of multiple pigmented BD in type V Fitzpatrick skin. Multiple BD is a therapeutic challenge with a tendency to recur. Here we present an otherwise healthy Indian male having multiple pigmented lesions of BD on sun-protected...
IMPORTANCE Dermoscopic triage algorithms have been shown to improve beginners' abilities for identifying pigmented skin lesions requiring biopsy. OBJECTIVE To estimate the diagnostic accuracy of the Triage Amalgamated Dermoscopic Algorithm (TADA) for pigmented and nonpigmented skin cancers. Secondarily, to compare TADAs performance to those of existing triage algorithms for the identification...
BACKGROUND Clinical experience of our single center in dealing with pigmented epibulbar lesions - melanocytic conjunctival tumors is presented. Since 2008 we use the topical treatment with mitomycin C (MMC) as an alternative or adjunctive method for excision in the treatment of melanocytic neoplasia of the conjunctiva. METHODS The retrospective case series of 85 patients with pigmented lesion...
OBJECTIVE To evaluate the performance of dermoscopists in diagnosing small pigmented skin lesions (diameter </= 6 mm) compared with an automatic multispectral computer-vision system. DESIGN Blinded comparison study. SETTING Dermatologic hospital-based clinics and private practice offices. Patients From a computerized skin imaging database of 990 small (</= 6-mm) pigmented skin lesions, all ...
The purpose of this study was to assess the precision of automatic computerized measurement of parameters that may be useful in the differentiation of malignant melanoma from benign pigmented skin lesions, and also to determine the feasibility of quantitative monitoring of skin lesions over time. Ten independent sequences of images were acquired with a MelaFind multispectral digital dermoscope ...
Dermoscopy, in expert hands, increases accuracy, sensitivity and specificity in diagnosis of pigmented skin lesions of a single operator, compared with clinical examination. Simplified algorithmic methods have been developed to help less expert dermoscopists in diagnosis of melanocytic lesions. This study included 125 melanocytic skin lesions divided into melanocytic nevi, dysplastic nevi and t...
CASE REPORT A 78-year-old-woman presented with a corneal non-pigmented vascularised tumour of her left eye, of 2 months onset, but with no previous ocular disorders. Surgical excision was performed, and the histopathological study showed the lesion to be an atypical melanocytic nevus of the limbus. DISCUSSION Corneal pigmented lesions tend to occur as a result of conjunctival or sclerocorneal...
OBJECTIVE To assess physician, patient, and skin lesion characteristics that affect the number of benign skin lesions excised by primary care physicians for each skin cancer. DESIGN Prospective study collecting clinical, patient, and histopathologic details of excisions or biopsies of skin lesions by random samples of primary care physicians. SETTING Southeast Queensland involving tradition...
neurocutaneous melanosis (ncm) is a rare, congenital non-hereditary syndrome, characterized by multiple pigmented nevi. we report the radiologic findings of a newborn who had extensive cutaneous melanotic nevus with satellite lesions in the brain. ultrasound showed multiple echogenic foci in the cerebral parenchyma. subsequent mri confirmed these lesions as characteristic deposits of melanin. t...
