Nevus sebaceus of Jadassohn (NSJ) is a congenital cutaneous hamartoma mainly developing from pilosebaceous unit cells. NSJ has the potential to develop into a variety of benign and malignant tumors, which are not limited to sebaceous differentiation. The dynamical monitoring for the earliest malignant transformation is necessary. Herein, we report the combined noninvasive NSJ examination with videodermoscopy in polarized and non-polarized light and high-frequency ultrasound (HFUS) imaging at 33 and 50 MHz. Typical NSJ dermoscopic signs where described, the internal nevus structure and its location, depths, and margins with surrounded tissues were examined with high-frequency ultrasound. Some HFUS characteristics for NSJ were described. Videodermoscopy and high-frequency ultrasound combined examination could be useful for NSJ dynamical monitoring in order to detect malignant transformation and to define necessary and sufficient tissue excision volume in case of surgical treatment.

Aim: To compare the depth spread of basal cell carcinoma (BCC) measured by histological examination and high-frequency ultrasound (HFUS) imaging with 30-MHz and 75-MHz probes.Materials and methods: HFUS skin imaging was used to examine 27 BCCs. A specialized high-resolution digital ultrasound imaging system DUB (TPM GmbH, Germany) with 75-MHz and 30-MHz probes was used. After HFUS scanning, the BCCs biopsy samples were collected by punch biopsy or surgical excision for the morphological examination. Based on the histomorphology results obtained, the tumors were divided into thin (≤1 mm invasion depth) and thick (>1 mm invasion depth). Each BCC spread depth was measured during the HFUS examination with 75-MHz and 30-MHz ultrasound probes and morphological examination.Results: Thin BCCs average invasiondepth measured histologically was 0.494±0.212 mm. Its average depth obtained with HFU examination with 75-MHz and 30-MHz probes was 0.591±0.265 and 0.734±0.123 mm, respectively. High, statistically significant correlation betweenthe histological and 75 MHz HFU measurements was obtained (r=0.870). The correlation was weak (r=0.290) when using a 30 MHz transducer. The average thick BCC invasion depth values obtained with the histological examination and 30 MHz HFUS scanning was 1.845±0.718 mm and 1.995±0.699 mm, respectively. High, statistically significant (r=0.951) correlation between the thick BCC spread depth measured with 30 MHz transducer and histomorphological examination was obtained.Conclusions: In cases of BCCs with thickness of ≤1 mm, there was a high correlation (r=0.870) of the tumor spread depth between micromorphological measurements and the results obtained using a 75 MHz transducer and in cases of BCCs with thickness of >1 mm, a very high correlation (r=0.951) of the tumor spread depth was observed between histomorphometry and30 MHz transducer measurements.

Rationale: Type IV collagen is the main component of the basal membrane ensuring its integrity. Basal membrane destruction is associated with absent type IV collagen expression being directly related to an increased tumor invasion risk. Specifics of the protein expression in various morphological types of basal cell carcinoma have not been well described.Aim: To study the association between type IV collagen expression and basal cell carcinoma morphological structure and invasion potential.Materials and methods: We performed an immunohistochemistry analysis with anti-type IV collagen antibodies on 30 biopsy specimens of the skin involved with basal cell carcinoma.Results: The superficial multicentric type of basal cell carcinoma differed from the solid, micronodular, and infiltrative types by linear continuous type IV collagen expression (р<0.0083). Most often, there was no type IV collagen expression in the micronodular and infiltrative basal cell carcinomas; however, no significant difference of the solid type and each of the abovementioned types was found. Aggressive basal cell carcinoma types (micronodular and infiltrative, taken together) were significantly different (р=0.033) from the solid type by the absence of type IV collagen expression. Linear continuous expression was seen exclusively in basal cell carcinomas with the invasion of≤0.825 mm.Conclusion: We have identified the difference in type IV collagen expression depending on the morphological type of basal cell skin carcinoma, prevailing linear continuous expression in the superficial multicentric type and its absence in the micronodular and infiltrative types.

The paper presents information regarding a rare skin disease Gottrons carcinoid papillomatosis, for the first time described in 1932 by German dermatologist H.A. Gottron. Its development is associated with the preceding chronic dermatoses and disturbance of circulation in the lower extremities. Morphologically, Gottrons carcinoid papillomatosis of the skin is characterized by the development of pseudoepitheliomatous hyperplasia of epidermis. Clinical picture, dermatoscopy, ultrasound and histological studied were used for diagnosis. This disease should be differed from high differentiated squamous cell carcinoma of the skin, chronic ulcerous pyodermavegetans, lupus verrucosis, chromomycosis. We described our own clinical observation of Gottrons carcinoid papillomatosis of the skin, developed against a background of psoriasis.

Objective. To study the character and features of emotional disorders in patients of dermatological and cardiological profile. Emotional changes, accompanying many somatic diseases, have a negative effect and aggravate their course, worsening the quality of life and functioning. Materials and methods. 68 persons, divided into two groups, participated in a single-stage study: group I included 38 patients with dermatoses without any concomitant diseases of the internal organs; group II 30 cardiological patients without dermatological pathology in anamnesis. Complex research included general clinical and laboratory methods as well as psychological study using the Hospital Anxiety and Depression Scale HADS, Zung Self-Rating Depression Scale, Montgomery Asberg Depression Scale, Spielberger Hanin Anxiety Scales. To assess the results, the methods of parametric and nonparametric statistics were used. Results. When assessing the parameters by the Hospital Anxiety and Depression Scale HADS, in dermatological patients clinically and subclinically expressed anxiety was manifested more evidently, and in cardiological patients, it was depression. According to the data obtained by the Zung and Hamilton scales, depression also predominated in cardiological patients but anxiety symptoms and disorders reliably more often were observed in patients of dermatological profile. As for studying depression using the Montgomery-Asberg scale, in dermatological patients it was revealed less often, in the structure of symptoms there prevailed a small depressive episode. According to Spielberger Hanin Scale, anxiety was more expressed in dermatological patients. Conclusions. Emotional disorders in dermatological and cardiological patients are reliably different. In dermatological patients, they are characterized by increased anxiety in case of an insignificant depressive disorder. In cardiological patients, there prevail depressive changes, especially mild depression; anxiety symptomatology is not expressed.
