BACKGROUND: Current staging systems have limitations in stratifying high-risk cases of cutaneous squamous cell carcinoma (cSCC). Tumor budding (TB) has emerged as a potential prognostic factor in various cancers. OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the prognostic significance of TB in predicting lymph node metastases (NM) in cSCC. METHODS: A comprehensive search of the PubMed, Web of Science, EMBASE, and Cochrane databases was conducted. Studies investigating the association of TB using a 5-bud cut-off and NM in cSCC were included. A meta-analysis was performed using odds ratios (OR) to evaluate the association between TB and NM. RESULTS: Six retrospective studies comprising 793 cSCC patients were included. The random-effects analysis showed a significant association between high TB (≥5 buds) and NM (OR = 13.29, 95% CI = 5.55; 31.86). DISCUSSION: Tumor budding is a promising histopathologic feature for predicting NM in cSCC. The results show a strong association between high TB and NM, supporting its utility as a risk factor for NM in cSCC. Its inclusion in clinical practice and cSCC staging might be helpful in the stratification of high-risk cases and guide optimal management strategies for each patient. However, further investigation is needed to determine standardized reporting guidelines for TB in cSCC.

Pilonidal sinus is an acquired chronic inflammatory condition associated with the penetration of hair fragments into the skin. In the pathogenesis of most of these cases, a traumatic event initiates the process allowing the introduction of the hairs into the skin. We report an unusual case of acquired pilonidal sinus as a consequence of the unconscious habit of chewing on the hairs in a 12-year-old girl. Although most commonly located in the gluteal cleft, it has been reported in several areas of the body (including face), but to the best of our knowledge, this is the first report in the oral cavity. Our case presented as a palatal and vestibular fistula in a patient who suffered from an undiagnosed peculiar form of hair pulling disorder that involved hair chewing but not trichophagia.

Reconstruction of surgical defects after wide local excision of acral melanoma on the sole should allow patients to walk and bear weight. Moreover, certain options such as local transposition flaps can compromise follow-up. We present a case series of surgical defects on weight-bearing areas of the sole reconstructed using a synthetic dermal matrix and a split-thickness skin graft. This approach prevents surrounding tissue displacement and results in good functional outcomes assessed by baropodometry and computer-based podoscopy.
