Reconstruction of retroauricolar surgical defect using the "jigsaw puzzle" advancement flap.

We present the case of a 55-year-old male patient who came to our attention because of a basal cell carcinoma of the right retroauricolar area, near the mastoid-auricle border. The tumor had a size of about 1.5 cm. Repairing retroauricolar surgical defects may be actually very challenging, firstly because an incorrect reconstruction may result in severe deformities which are extremely hard to conceal; so, we decided to employ the "jigsaw puzzle" advancement flap, a versatile flap, firstly successfully used in the reconstruction of a nasal ala defect.

Comparison of quality of life between melanoma and non-melanoma skin cancer patients.

The impact of skin cancers on patients' health-related quality of life (HRQoL) is often overlooked, and direct comparisons between melanoma and non-melanoma skin cancer (NMSC) are rare. Objectives: The aim of this study was to compare HRQoL in patients with melanoma and NMSC. Participants were unselected, consecutive adult patients with a diagnosis of melanoma at the time of wide excision, or NMSC at the time of surgery. HRQoL was measured using the two scales of Skindex-17. The 12-item General Health Questionnaire (GHQ-12) was used to identify patients with possible anxiety or depression. The study population included 433 patients: 65 with melanoma and 368 with NMSC. Skindex-17 symptom mean scores were higher in NMSC than in melanoma patients. Melanoma patients had significantly higher scores for the item "feeling depressed". The percentage of GHQ-12 cases (with possible non-psychotic, minor psychiatric disorders) was significantly higher in patients with melanoma (32.8%) compared to NMSC patients (8.7%). NMSC places a greater burden of symptoms on patients than melanoma, while the psychological impact of melanoma is higher.

Interleukin-17 and interleukin-22 promote tumor progression in human nonmelanoma skin cancer.

Interleukin-17 (IL-17) and IL-22 have been reported to play critical roles in autoimmunity and inflammation but information about their role in cancer is limited. In this study, we investigated the role of IL-17 and IL-22 in the progression of human skin basal-cell carcinoma (BCC) and squamous-cell carcinoma (SCC). We found that both tumor types are infiltrated with an high number of IL-17(+) and IL-22(+) T lymphocytes, as demonstrated by immunohistochemistry and by FACS analysis performed on peritumoral T-cell lines isolated from skin biopsies. In vitro studies demonstrated that proliferation and migration of the BCC- and SCC-cell lines M77015 and CAL27 were increased by IL-17 and IL-22. Moreover, IL-17, alone or in combination with TNF-α, was able to induce the production of two cytokines important for tumor progression, IL-6 and IL-8, in CAL27. We also showed that IL-17 upregulated NF-κB signaling, while IL-22 activated the STAT3 pathway and the antiapoptotic AKT protein in M77015 and CAL27. Finally, in vivo experiments demonstrated that IL-17 and IL-22 enhanced tumor growth in nude mice injected with CAL27. Altogether, our findings indicate that high levels of IL-22 and IL-17 in the BCC and SCC microenvironment promote tumor progression.

Erbium:YAG laser and cultured epidermis in the surgical therapy of stable vitiligo.

OBJECTIVE: To induce complete and reproducible repigmentation of large "stable" vitiligo lesions by means of autologous cultured epidermal grafts using a rapid, simple, and minimally invasive surgical procedure. DESIGN: Achromic epidermis was removed by means of appropriately settled erbium:YAG laser, and autologous epidermal grafts were applied onto the recipient bed. Melanocyte content was evaluated by dopa reaction. The percentage of repigmentation was calculated using a semiautomatic image analysis system. SETTING: A biosafety level 3-type cell culture facility, a surgical ambulatory department, and a dermatological department in a hospital. PATIENTS: Twenty-one patients with different types of vitiligo were admitted to the study and treated with autologous cultured epidermal grafts. Inclusion criteria were failure of at least 2 standard medical approaches; no therapy for at least 12 months; no progression of old lesions or appearance of new lesions; no Koebner phenomenon within the past 18 months; and no autoimmune disorders. RESULTS: The average percentage of repigmentation in 21 patients was 75.9% (1759.7 cm2 repigmented/2315.8 cm2 transplanted). Three patients showed a reactivation of their vitiligo and did not show repigmentation. The remaining 18 patients, with 43 distinct lesions, showed an average percentage of repigmentation of 90% (1759.7 cm2 repigmented/1953.4 cm2 transplanted). CONCLUSIONS: Under appropriate conditions, cultured epidermal grafts induce complete repigmentation of stable vitiligo lesions. Erbium:YAG laser surgery can supply a fast and precise tool for disepithelialization, hence allowing treatment of large vitiligo lesions during a single surgical operation.
