Benign melanosis and malignant melanoma of penis and male urethra.

Malignant melanoma of the penis and male uretha are unusually aggressive tumors which only rarely are cured by radical surgery. Melanosis of the penis may be confused with malignant melanoma, and we report a case of melanosis originally diagnosed and treated as melanoma with survival for twenty years. We contrast this with another case of malignant penile melanoma with a fatal outcome.

Penile disorders in two paraplegics.

We present two rare cases of paraplegics with remarkable sequelae of the penis due to long-term usage of a condom-catheter. One involved hypertrophy of the glans prepuce, and the other had severe constriction of the distal portion of the corpus penis with two fistulae.

Ectopic lesion of schistosomiasis of the penis simulating an early carcinoma.

A case of ectopic lesion of Schistosoma haematobium of the penis with extensive tissue destruction, simulating an early carcinoma of the penis and almost resulting in an autoamputation of the crown of the penis, is presented. The penis was surgically repaired and the patient treated with ambilhar. In schistosoma endemic area, it is important to think of ectopic schistosoma lesion by such a presentation. Existing theories to explain the presence of schistosoma eggs in locations outside the portal-caval system were reviewed and another one was advanced: its being sexually transmitted.

Progressive T cell exhaustion and predominance of aging tissue associated macrophages with advancing disease stage in penile squamous cell carcinoma.

Penile squamous cell carcinoma (PSCC) is a rare malignancy with limited understanding of the tumor immune microenvironment (TIME). The interplay between PSCC and the immune system across disease progression and HPV infection status remains poorly characterized. This study aims to assess the TIME changes from localized to advanced disease and between HPV-positive versus negative tumors to identify potential immune evasion mechanisms in advanced PSCC. scRNA-seq was performed on ten PSCC tissue samples from penile, lymph node and distant metastatic sites with four matched penile and lymph node samples to understand the cellular heterogeneity within PSCC tumors. Analysis of immune cell populations and transcriptional hallmarks were performed stratified by localized (pT1-3, N0) versus advanced (N1-3, M0 or any N, M1) disease states and HPV infection status. We observed significant differences in immune cell infiltration between localized and advanced PSCC disease states and by HPV status. Advanced disease states demonstrated an exhausted immune phenotype, characterized by terminally exhausted CD8+ T cells, M2-like macrophages and hypoxic signature, while localized disease states demonstrated an active innate immune system characterized by increased DCs. HPV-negative tumors displayed low immune cell infiltration while HPV-positive tumors demonstrated an immune exhausted phenotype. These findings offer valuable insights into the evolving PSCC immune landscape, paving the way for the development of potential therapeutic approaches for advanced PSCC.

Lesions of the canine penis and prepuce.

In 185 dogs treated for penile or preputial problems, 197 lesions were observed including 86 tumors (of which 84 were transmissible venereal tumors), 40 cases of balanophosthitis, 38 wounds, 14 urethral calculi and one urethral stenosis. In addition, 14 cases of paraphimosis, one phimosis and 4 fractures of the os penis were seen. This report discusses the clinical signs, treatment and results of penile-preputial disease.
