Condyloma acuminatum is a common sexually transmitted disease caused by human papillomavirus infection and is a benign hyperplastic lesion of the genital and perianal areas. The principle of its treatment is to remove the visible warts as much as possible and to prevent recurrence. Traditional treatment methods of condyloma acuminatum, such as CO laser, liquid nitrogen freezing, surgery, and topical medications, can remove warts. However, these methods have disadvantages such as pain, high recurrence rates, long treatment cycles, and scarring. Aminolevulinic acid/photodynamic therapy (ALA-PDT), a safe and effective method, has been widely used to treat condyloma acuminatum in recent years. Condyloma acuminatum occurs relatively rarely in elderly patients, in whom treatment is difficult owing to poorer physiological function. We successfully treated an 87-year-old patient with a giant condyloma acuminatum of the glans penis using six sessions of ALA-PDT at 7-day intervals and obtained satisfactory results. No recurrence was observed during a 6-month follow-up. Therefore, ALA-PDT is worth popularizing in clinical practice.

Penile metastases from urothelial carcinoma are rare (1-8%). They most often (65%) occur within 18 months of diagnosis of the primary lesion and their prognosis is poor, with survival rarely exceeding 20 months. Treatment of cavernous metastases is multidisciplinary. The best results in terms of overall survival have been obtained with amputation of the penis combined with chemotherapy. We present a case of a 62-year-old male who presented with a metastasis of the penis. This was confirmed by MRI and biopsy, which confirmed the urothelial origin of the metastasis. The patient had undergone radical cystoprostatectomy for an invasive bladder tumor six months earlier. The patient died 10 days after the biopsy due to a significant deterioration in his general condition and the onset of consciousness disorders.

BACKGROUND
Immediate lymphatic reconstruction (ILR) has traditionally required a fluorescent-capable microscope to identify lymphatic channels used to create a lymphaticovenous bypass (LVB). Herein, a new alternative method is described, identifying lymphatic channels using a commercially available handheld fluorescence imaging device.
METHODS
This was a single-center study of consecutive patients who underwent ILR over a 1-year period at a tertiary medical center. Intradermal injection of fluorescent indocyanine green dye was performed intraoperatively after axillary or inguinal lymphadenectomy. A handheld fluorescent imaging device (SPY-PHI, Stryker) rather than a fluorescent-capable microscope was used to identify transected lymphatic channels. Data regarding preoperative, intraoperative, and outcome variables were collected and analyzed.
RESULTS
The handheld fluorescent imaging device was successfully able to identify transected lymphatic channels in all cases (n = 15). A nonfluorescent-capable microscope was used to construct the LVB in 14 cases. Loupes were used in one case. In 13 cases, ILR was unilateral. In two cases, bilateral ILR was performed in the lower extremities. All upper extremity cases were secondary to breast cancer (n = 7). Lower extremity cases (n = 8) included extramammary Paget disease of the penis, ovarian cancer, vulvar squamous cell carcinoma, squamous cell carcinoma of unknown origin, soft tissue sarcomas, cutaneous melanoma, and porocarcinoma.
CONCLUSIONS
ILR, using indocyanine green injection with a handheld fluorescent imaging device, is both safe and effective. This method for intraoperative identification of lymphatic channels was successful, and LVB creation was completed in all cases. This approach makes ILR feasible when a fluorescent-capable microscope is unavailable, broadening access to more patients.

Human Genomics Dec 2023The effect of SPP1 in squamous cell carcinoma of the penis (PSCC) remained unknown. We attempted to clarify the function of the SPP1 gene in PSCC.
BACKGROUND
The effect of SPP1 in squamous cell carcinoma of the penis (PSCC) remained unknown. We attempted to clarify the function of the SPP1 gene in PSCC.
METHOD
Eight paired penile cancer specimens (including penile cancer tissue, paracancerous tissue, and positive lymph node tissue) subjected to whole transcriptome sequencing were analysed to identify differentially expressed genes. We used immunohistochemistry to detect the expression of SPP1 protein and immune cell related proteins in penile cancer tissue. Then, we performed weighted gene coexpression network analysis (WGCNA) to identify the genes related to SPP1 in penile cancer tissue and positive lymph node tissue. Based on the GSE57955 dataset, the CIBERSORT and ssGSEA algorithms were carried out to investigate the immune environment of PSCC. GSVA analysis was conducted to identify the signaling pathways related to SPP1 subgroups. Enzyme-linked immunosorbent assay (ELISA) method was adopted to detect SPP1 level in the serum of 60 patients with penile cancer.
RESULTS
Differential analysis indicated that SPP1 was the most differentially upregulated gene in both penile cancer tissues and positive lymph node tissues. Survival analysis suggested that the prognosis of the low-SPP1 group was significantly poorer than that of the high-SPP1 group. Subsequently, immune-related bioinformatics showed that SPP1 was significantly associated with B cells, CD8 + T cells, CD4 + T cells, macrophages, helper T cells, neutrophils and dendritic cells. The immunohistochemical results showed that the high-SPP1 group was characterized by relatively high expression of CD16 and relatively low expression of CD4. GSVA analysis indicated that high-SPP1 group was significantly associated with immune-related pathways such as PD-L1 expression and the PD-1 checkpoint pathway in cancer and the TNF signaling pathway. ELISA demonstrated that the serum level of SPP1 in patients with positive lymph node metastasis of penile cancer was significantly higher than that in patients with negative lymph node metastasis of penile cancer.
CONCLUSION
Our study shows that the SPP1 gene might be an effective biomarker for predicting the prognosis and the efficacy of immunotherapy in PSCC patients.

Penile cancer is a rare genitourinary malignancy for which limited treatment options exist beyond primary surgical resection. Metastatic lymphadenopathy represents a particularly poor prognosis with a lack of literature to suggest the effectiveness of radiation or systemic therapies. Our case documents an inguinal recurrence of penile squamous cell carcinoma not amenable to surgical intervention demonstrating complete response to salvage radiotherapy in the palliative setting. These observations propose the need for further research around the utility of radiotherapy in the management of metastatic penile malignancies.

Extramammary Paget disease (EMPD) is a rare adenocarcinoma that usually occurs in areas of the body that are rich in apocrine sweat glands. Great depth of tumor invasion is a well-known risk factor for worse prognosis. Paget cells usually are limited to the epidermis, whereas invasive EMPD, which infiltrates the dermis, is relatively rare. It is even rarer for the tumor to spread beyond the dermis. Only 3.1% of patients with EMPD of the penis and scrotum have exhibited infiltration of the subcutaneous fat layer. We report a case of a 62-year-old male with EMPD that invaded the subcutaneous fat layer. He presented with a several-year history of a slowly expanding erythematous plaque with the hypopigmented area on the left penoscrotum. One month before presentation, the patient had undergone punch biopsy at another hospital and diagnosed with EMPD. He had no personal history of urogenital cancers. The patient was treated with Mohs micrographic surgery, and negative margins were achieved after four stages. The histopathologic findings revealed Paget cells scattered throughout the epidermis. At the hypopigmented area, Paget cells extended to the subcutaneous fat layer with lymphovascular invasion. There was no evidence of recurrence at seven months postoperatively. Herein, we describe a case of hypopigmented EMPD that infiltrated the subcutaneous layer, which rarely has been reported in Korea.

INTRODUCTION
Little research has investigated the prevalence and distribution of the diverse pathologies of non-squamous cell carcinoma (non-SCC) of the penis. Although rare in clinical practice, these cancers have become a focus of greater importance among patients, clinicians, and researchers, particularly in developing countries. The principal objective of this study was to analyze the major types of penile non-SCC, elucidate common treatment pathways, and highlight outcomes including 5-year survival.
MATERIALS/METHODS
The Surveillance, Epidemiology, and End Results (SEER) database was queried between 2000 and 2018 to identify a retrospective cohort of patients with penile non-SCC. Demographic information, cancer characteristics, diagnostic methods, treatments administered, and survival were investigated.
RESULTS
A total of 547 cases of penile non-SCC were included in the analysis. The most prevalent non-SCC cancers included epithelial neoplasms, not otherwise specified (NOS) (15.4%), unspecified neoplasms (15.2%), basal cell neoplasms (13.9%), blood vessel tumors (13.0%), nevi and melanomas (11.7%), and ductal and lobular neoplasms (9.9%). Over half (56.7%) of patients elected to undergo surgical intervention. Patients rarely received systemic therapy (3.8%) or radiation (4.0%). Five-year survival was 35.5%. Patients who underwent surgery had greater annual survival for 0-10 years compared to those who did not have surgery. Significant differences in survival were found between patients who had regional, localized, and distant metastases ( < 0.05). A significant difference in survival was found for patients married at diagnosis versus those who were unmarried at diagnosis ( < 0.05). Lower survival rates were observed for patients older than 70 years.
DISCUSSION
Although less prevalent than SCC, penile non-SCC encompasses a diverse set of neoplasms. Patients in this cohort had a high utilization of surgical management leading to superior outcomes compared to those not receiving surgery. Radiation is an uncommonly pursued treatment pathway. Patient demographics and socioeconomic variables such as marital status may be valuable when investigating cancer outcomes. This updated database analysis can help inform diagnosis, management, and clinical outcomes for this rare group of malignancies.
