Introduction: In the case of clinically negative inguinal regions in penile cancer, the treatments proposed might vary from careful observation to radical dissection for all patients. We evaluated the effectiveness of the sentinel lymph node biopsy using lymphoscintigraphy in patients with penile cancer and at least one negative inguinal region.
Materials And Methods: In 18 patients, biopsy of the sentinel lymph node from the 32 negative inguinal regions and modified radical lymphadenectomy in these regions regardless of the biopsy results was performed. Clinical staging, pathological results of the sentinel and the other lymph nodes removed during lymphadenectomy, tumor behavior, local and inguinal recurrence and specific disease mortality were accessed.
Results: The mean age of the study sample was 57.7 years (44 - 81 years) and the sentinel lymph node presented 0% false negative 66% sensitivity, and 79.3% specificity when compared with the modified inguinal lymphadenectomy as the gold standard treatment.
Conclusion: Sentinel lymph node biopsy is a feasible method of assessing the presence of regional metastasis in patients with penile cancer and clinically negative inguinal regions. However, the optimal lymphoscintigraphy technique is still in evolution and requires further optimization at high volume centers.

Background: Acral melanoma is associated with poor prognosis. Studying the characteristics and prognosis of Caucasian patients is crucial to understand the distinct features of this tumor.
Objectives: To analyze the epidemiological, clinicopathological, and prognostic features of acral melanoma in Caucasian patients.

Objective: This retrospective study aimed to evaluate the predictive value of the preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) findings of mass lesions for predicting sentinel lymph node (SLN) metastasis in early breast cancer.
Methods: A total of 310 patients with suspicious mass lesions detected in preoperative MRI who subsequently underwent surgery and SLN biopsy (SLNB) between September 2015 and September 2022 were analyzed. The relationship between DCE-MRI and DWI findings and SLNB positivity was analyzed.

Institute for Plastic Surgery, Southern Illinois University School of Medicine, Springfield, USA.
Background: Aggressive digital papillary adenocarcinoma (ADPA) is a rare skin adnexal tumor with a predilection for the hand. The presentation, treatment, and outcomes of ADPA remain poorly defined due to the scarcity of reports and low-level evidence of published findings.
Methods: We performed a meta-analysis following Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines with the intent to provide hand surgeons a better understanding of the diagnosis and treatment of the disease.
