PURPOSE: Basal cell carcinoma (BCC) is a locally invasive skin tumor which can be subdivided into a circumscribed nodular and an invasive fibrosing subtype. There is increasing evidence that macrophages play an important role in interacting between tumor cells and their microenvironment, thereby affecting not only the invasive potential but also the patients' prognosis. Thus, we wanted to compare these two BCC variants with regard to tumor-related inflammation, COX-2 expression, distribution and polarization of tumor-associated macrophages...

Objective: The aim of this study is to investigate the expression and clinical significance of monocarboxylate transporter 1 (MCT-1) and p53 in laryngeal squamous cell carcinoma (LSCC). Method: Immunohistochemical staining of MCT-1 and p53 was carried out in 41 cases of laryngeal squamous cell carcinoma embedded in paraffin, and the relationship between positive expression and clinicopathological data was evaluated. All data were analyzed by SPSS software (Windows version 21.0). Result: In normal mucosa p53 expression was absent; while, the basal "stem cell" layer is highly enriched in MCT-1...

REVIEW
J Welzel, S Schuh
Optical coherence tomography (OCT) has become established in routine diagnosis in dermatology only in the last few years. The reason is that the skin is a challenge for OCT as a strong scattering medium, because only a very small proportion of photons is reflected and can be used for imaging. In addition, in most cases a visual assessment or a biopsy is sufficient. Nevertheless, the main field of application in dermatology is the diagnostics of epithelial skin tumors. The OCT is suitable for the early recognition of small, clinically and light microscopically unspecific basal cell carcinomas as well as for the differential diagnosis of other tumors and precancerous lesions...

Salt Inducible Kinase2 (SIK2) has been shown to contribute to tumorigenesis in multiple tumor types in a dichotomous manner. However, little is known about its contribution to breast malignancies. Here, we report SIK2 as a potential tumor suppressor in breast cancer whose expression was reduced in tumor tissues and breast cancer cell lines compared to normal counterparts. In vitro loss- and gain-of-function experiments combined with xenograft studies demonstrated that SIK2-mediated attenuation of proliferation and survival of breast cancer cells with parallel inhibition of both Ras/Erk and PI3K/Akt pathways...

Microphthalmia-associated transcription factor (MiTF) is used as a marker of melanocytic differentiation. However, MiTF immunoexpression has also been observed in histiocytes, macrophages, smooth muscle cells and fibroblasts, which raise the concern of fibrohistiocytic (FH) lesions being misdiagnosed as melanoma based on MiTF immunoreactivity. MiTF has been known to be positive in FH tumors, but this is the first study evaluating ninety-three fibrohistiocytic neoplasms to understand and delineate the staining pattern of MiTF in these tumors...

Giant basal cell carcinoma (GBCC) is defined as a tumor ≥5 cm in diameter. GBCC of scalp usually requires extended resection of soft tissues, calvarium, and dura. In this study, we present 5 patients with GBCC of head, who underwent a single-stage combined scalp, calvarium, and dural reconstruction. Herein, we aim to discuss reconstruction methods, cerebrospinal fluid (CSF) leakage, duration of hospital stay, and tumor recurrency. Peroperative and postoperative follow-ups, defect areas, and performed calvarium reconstruction methods of 5 patients, who underwent complex scalp and calvarium reconstruction after GBCC between year 2010 and 2017, were retrospectively maintained...

Growth differentiation factor 15 (GDF15) is a divergent member of the transforming growth factor-β (TGF-β) superfamily that has been associated with colorectal cancers (CRC). However, the role of GDF15 in the progression of CRC remains unknown. We demonstrated that GDF15 expression was higher in fresh CRC tissues than in adjacent normal tissues. Moreover, we found that GDF15 overexpression significantly facilitated cell viability, cell invasion and migration (p < .01 or p < .05). The protein expression of N-cadherin, vimentin and Twist1 were up-regulated by GDF15 overexpression, while E-cadherin was down-regulated...

Basal cell carcinoma (BCC), the most common type of skin cancer in the world, usually arises in sun-exposed areas of the skin. The therapeutic approach to periocular BCC has changed in the last few years. Currently the treatment, considering the delicate localization of the disease, must not only ensure complete recovery from the neoplastic disease, but must also satisfy functional and aesthetic criteria. In this study we tried to evaluate the efficacy of CO2 laser and photodynamic therapy in periocular BCC...

Although rare, masses and mass-like lesions of developmental and genetic origin may affect the paediatric craniofacial skeleton. They represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation and disfigurement. The most common lesions include fibrous dysplasia, dermoid cysts, vascular malformations and plexiform neurofibromas. Less common lesions include torus mandibularis and torus palatinus, cherubism, nevoid basal cell carcinoma syndrome, meningoencephalocele and nasal sinus tract...

Mohs micrographic surgery (MMS) is a specialized technique for treating skin malignancies that offers the highest cure rate by allowing histological evaluation of the entire peripheral and deep margins. MMS also maximally preserves as much uninvolved, normal adjacent tissue as possible, allowing for the best cosmetic and functional outcomes. When used for appropriate indications, this technique is also more cost-effective than other treatment modalities. In this article, the authors will discuss the development of MMS, the steps involved in this procedure, and the indications for this technique...

Small cell carcinoma (SmCC) of the bladder is a rare disease. We retrospectively studied a large series of bladder SmCC from a single institution. The patients included 69 men and 12 women with a mean age of 68years. Most bladder SmCC were presented at advanced stage with tumors invading the muscularis propria and beyond (n=77). SmCC was pure in 27 cases and mixed with other histologic types in 54 cases, including urothelial carcinoma (UC) (n=32), UC in situ (n=26), glandular (n=14), micropapillary (n=4), sarcomatoid (n=4), and squamous (n=3), and plasmacytoid (n=1) features...

BACKGROUND: Rare prostate carcinomas aberrantly express p63 and have an immunophenotype intermediate between basal and luminal cells. Here, we performed gene expression profiling on p63-expressing prostatic carcinomas and compared them to usual-type adenocarcinoma. We identify ETS2 as highly expressed in p63-expressing prostatic carcinomas and benign prostate basal cells, with lower expression in luminal cells and primary usual-type adenocarcinomas. METHODS: A total of 8 p63-expressing prostate carcinomas at radical prostatectomy were compared to 358 usual-type adenocarcinomas by gene expression profiling performed on formalin fixed paraffin embedded tumor tissue using Affymetrix 1...

Basal cell carcinoma of the umbilicus is very rare. The nodular subtype is the main representative. Giant basal cell carcinomas represent around 1% of all basal cell carcinomas. The hedgehog pathway inhibitor vismodegib is indicated for advanced basal cell carcinoma and CD56-negative immunostaining seems indicative for successful treatment. A 54-year-old man presented a 10 cm × 14 cm large and 4.5 cm deep morphea-form basal cell carcinoma with faint immunohistochemical CD56 expression arising from the umbilicus...

Basal cell carcinoma (BCC) is the most frequent human cancer and is becoming an important health problem in an ageing population. Based on their clinical and histological characteristics, thick BCC are typically divided into low-risk nodular and high-risk infiltrative subtypes, although the underlying mechanisms are poorly understood. We have identified molecular mechanisms that explain the aggressiveness of high-risk infiltrative BCC, with a potential direct clinical impact. In this study, we first show that fibroblasts, TGFβ and fibronectin are found preferentially in infiltrative human BCC...

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) represents the most common form of skin cancer after basal cell carcinoma, and can be both locally invasive and metastatic to distant sites. Growth rate (GR) has been poorly evaluated in cSCC, despite clinical evidence suggesting that GR is an important risk factor in cSCC. AIM: To analyse the influence of GR in cSCC prognosis. METHODS: We retrospectively evaluated GR in a series of 90 cSCCs and tried to correlate GR with prognosis in cSCC...

Autophagy is a key biological phenomenon conserved from yeast to mammals. Under basal conditions, activation of autophagy leads to the protein degradation as well as damaged organelles for maintaining cellular homeostasis. Deregulation of autophagy has been identified as a key mechanism contributing to the pathogenesis and progression of several liver diseases, including hepatocellular carcinoma (HCC), one of the most common and mortal types of cancer. Currently used treatment strategies in patients with HCC result in variable success rates...
