Efficacy and safety of diphenylcyclopropenone alone or in combination with anthralin in the treatment of chronic extensive alopecia areata: a retrospective case series.

Background: Some patients with chronic extensive alopecia areata (AA) may be refractory to topical immunotherapy. Combination therapy is recommended for such patients. Efficacy and safety of a combination therapy with diphenylcyclopropenone (DPCP) and anthralin in chronic extensive AA is unknown.

Diagnostic reliability of the Tzanck smear in dermatologic diseases.

Background: The Tzanck smear is a simple, easily applicable, rapid, and inexpensive test for the diagnosis of erosive vesiculobullous, tumoral, and granulomatous diseases. The diagnostic accuracy of the Tzanck smear is known, but its diagnostic reliability has been evaluated only in herpetic infections and basal cell carcinoma.

Objectives: The aim of this study was to evaluate the diagnostic reliability of the Tzanck smear in erosive vesiculobullous, tumoral, and granulomatous diseases.

The contribution of teledermatoscopy to the diagnosis and management of non-melanocytic skin tumours.

We examined the contribution of dermatoscopy to the reliability of the diagnosis and management of non-melanocytic skin tumours using store-and-forward teledermatology. A total of 150 patients with non-melanocytic skin tumours were enrolled into the study. The reliability of the diagnoses and management plans was measured by comparing teledermatology with face-to-face examination; the effect of adding dermatoscopy images was also analysed.

Dermatoscopy versus Tzanck smear test: a comparison of the value of two tests in the diagnosis of pigmented skin lesions.

Background: Dermatoscopy is the most commonly used noninvasive tool for the diagnosis of pigmented skin lesions, but few studies have investigated the value of cytology in the identification of those lesions.

Objective: We compared the accuracy of dermatoscopy with that of the Tzanck smear test in the diagnosis of pigmented skin lesions, and in differentiating melanocytic from nonmelanocytic lesions.

Methods: Two dermatologists used either dermatoscopy or the Tzanck smear test to evaluate pigmented skin lesions, and the diagnostic accuracy of those methods was determined.

The Tzanck smear test: rediscovery of a practical diagnostic tool.

The Tzanck smear test is a simple, rapid, valuable, and cost-effective diagnostic method based on the investigation of characteristics of individual cells. In this method, materials are obtained by various techniques and then transferred to a glass slide. Slides can be stained with various dyes and then are examined under a light microscope.

A case with two unusual findings: cutaneous leishmaniasis presenting as panniculitis and pericarditis after antimony therapy.

Background: Cutaneous leishmaniasis is a parasitic disease caused by a Protozoan. Clinically and histopathologically, it can be confused with various dermatologic diseases.

Methods: We report a case of cutaneous leishmaniasis (CL) with two unusual findings.

A useful alternative approach for the treatment of well-demarcated Basal cell carcinoma: surgical excision and margin control with tzanck smear test.

Objective: To analyze the accuracy of the Tzanck smear test (TST) for margin control in surgery for well-demarcated basal cell carcinoma (BCC).

Methods And Materials: Twenty-one patients with well-demarcated BCC were included in this study. After local anesthesia, the tumors were excised.

More experiences with the Tzanck smear test: cytologic findings in cutaneous granulomatous disorders.

Background: Granulomatous dermatitis is a distinctive histopathologic cutaneous reaction pattern against various infectious and noninfectious agents. Cytologically, granulomatous dermatitis shows granulomas and multinucleated giant cells. Various etiologic agents of granulomatous diseases can also be identified.

The value of Tzanck smear test in diagnosis of erosive, vesicular, bullous, and pustular skin lesions.

Background: Tzanck smear is generally used for the diagnosis of the pemphigus group of autoimmune bullous diseases and mucocutaneous herpesvirus infections. There are only a few studies in the literature investigating its diagnostic value.

Objectives: We aimed to investigate Tzanck smear findings and to determine the diagnostic value of this test in moist (erosive, vesicular, bullous, and pustular) skin lesions.

Cutaneous manifestations in brucellosis: a prospective study.

Brucellosis remains an important public health problem in Turkey, just as it is in other regions of the world. This study was conducted to determine the types and rates of cutaneous lesions that occur in patients with brucellosis. Brucellosis was diagnosed by standard tube agglutination testing for Brucella antibodies at a titer of 1/160 or higher in the presence of compatible clinical findings.

Efficacy and safety of the short-pulse erbium:YAG laser in the treatment of acquired melanocytic nevi.

Background: Various laser systems have been used in the treatment of acquired melanocytic nevi. However, CO2 lasers may cause scarring, and some nevi cannot be removed with pigment-specific lasers completely. To date, no study has evaluated the efficacy and safety of an erbium:yttrium-aluminum-garnet (YAG) laser, with its small penetration depth and fewer adverse effects, in the treatment of acquired melanocytic nevi.

A comparison of teledermatology using store-and-forward methodology alone, and in combination with Web camera videoconferencing.

We compared the diagnostic accuracy of conventional asynchronous teledermatology ('store-and-forward' [SAF]) with a combined technique, in which SAF methodology was used first, followed by a videoconference using low-cost Web cameras. The study involved 228 patients with 242 lesions. For each case, two independent teledermatologists (A and B) evaluated digital images and clinical information by the conventional SAF method and gave a single diagnosis.

Familial cutis tricolor: a possible example of paradominant inheritance.

Cutis tricolor is a recently described skin disorder characterized by the coexistence of congenital hyper- and hypopigmented macules adjacent to each other on a background of normal skin. It has been considered to represent an example of didymosis (twin spotting), which is a particular form of loss of heterozygosity. Cutis tricolor may occur as a cutaneous feature of various multisystem birth defects.

Segmental lentiginosis with ipsilateral nevus depigmentosus: another example of twin spotting?

We report a patient with unilateral lentiginosis and ipsilateral nevus depigmentosus. She had no other cutaneous or extracutaneous abnormalities. The coexistence of segmental lentiginosis and nevus depigmentosus may be explained as a twin-spot phenomenon.
