The main metastatic sites of renal cancer are the lungs, bone, liver, and brain. Dissemination of clear cell renal carcinoma to the rectum is very rare, with only a few sporadic cases published in the literature. The clinical presentation is usually dominated by lower gastrointestinal haemorrhage. We report the 5th case in the literature of a rectal metastasis of clear cell renal carcinoma, revealed by a lower gastrointestinal haemorrhage occurring 8 years after the initial nephrectomy.

The incidence of erosion of inflatable penile prosthesis (IPP) components into adjacent organs is low (<0.1 %). During a transurethral resection of the prostate (TURP) in a patient with prior IPP placement, we encountered IPP tubing that had eroded into the prostate. The pump and cylinders were later explanted through a penoscrotal approach, with the reservoir drained and retained with plan for follow up cystoscopy in 4–6 weeks. Cystoscopy 1 month later demonstrated reservoir erosion into the bladder lumen. An open cystotomy was performed to retrieve the reservoir. This is the first reported case of IPP tubing eroding into the prostate.

We review a case of total penile skin replacement with split-thickness micromesh skin graft (micromesh STSG) due to paraffinoma.

This study presents the case of a 40-year-old male patient after renal transplantation. The CT scan revealed a large mass in the lower abdomen and pelvis, with a branch of the right external iliac artery intersecting the growth. After a comprehensive examination, it was shown that the mass originated from the transplanted kidney, and a radical nephrectomy (including the mass) was performed. We document a case of atypical angiomyolipoma (AAM) occurring in a transplanted kidney. This article reports the case study and a brief literature review of the clinical presentation, diagnosis and treatment of AAM.

Spermatocytic tumors are rare testicular cancers, accounting for less than 1 % of all testicular neoplasms, usually affecting older men. This report details a 35-year-old male with a spermatocytic tumor featuring extensive lymphovascular invasion. The patient had a painless, slow-growing right testicular mass, with normal serum tumor markers. Ultrasound and CT scans suggested malignancy. Post-orchiectomy, histopathology confirmed a spermatocytic tumor with polymorphic cells and lymphovascular invasion. Immunohistochemical staining was positive for SALL4 and CD117, negative for OCT4, AFP, and CD30. The patient underwent chemotherapy and remained recurrence-free for a year, highlighting the need for accurate diagnosis and long-term monitoring.

Traumatic neuromas are benign nerve sheath tumors resulting in overgrowth of nerve fibers of severed ends in which the axons to Schwann cell fascicles approaches a near 1:1 ratio. They occur when the nerve has been injured and continuity cannot be reestablished. Traumatic neuromas that arise in the penis are rare and are difficult to differentiate from condylomata without histopathologic analysis. Here, we present a case in which a patient presents with two ventral penile lesions in which excisional biopsy and histologic analysis proved to be diagnostic and curative.

Caval thrombus with intracardiac involvement is a rare condition that is associated with renal cell carcinoma. Few reports in literature describe this presentation with metastatic melanoma. Metastatic melanoma is known to involve the adrenal gland, although associated tumor thrombus extension into the renal vein and inferior vena cava is extremely rare. In this case report, we describe radical nephrectomy and adrenalectomy for metastatic melanoma.

Glomus tumors are rare mesenchymal neoplasms of the subcutaneous tissue, most frequently found in the distal extremities. They are typically benign, but malignant glomus tumors have been described in the literature. Here we present a patient found to have a unilateral renal mass with pathology displaying a primary renal glomus tumor with malignant features. Review of the literature reveals only three cases of malignant glomus tumors and five glomus tumors with malignant potential. As such, previous initial presentations, current criteria for glomus tumor malignancy, and previous treatment outcomes of these cases were reviewed.

Hypophosphatasia (HPP) is a rare genetic condition associated with poor bone mineralization, low serum alkaline phosphatase, high urinary pyrophosphate excretion, and nephrocalcinosis. Nephrocalcinosis is thought to develop due to the increased filtered loads associated with hypercalcemia and hyperphosphatemia, but the composition of these calcifications is incompletely understood. We report the first ever magnesium pyrophosphate (MgPPi) urinary stone, which prompted the new diagnosis of HPP in a 12-year-old boy. Stone analysis labs should include infrared spectra of PPi salts in their reference libraries to facilitate identification of these rare but clinically important stones.

We report the management of a 76-year-old male presenting with primary metastatic melanoma, prostatic carcinoma, and clear cell renal cell carcinoma. Each of the three cancers was identified via PSMA PET-CT, thought to be unique to prostate cancer identification. Management of this patient included axillary lymph node resection, radiation therapy, radical nephrectomy, and immunotherapy. This case emphasizes the need for a multimodal approach and a broad differential diagnosis when managing cancer patients. Furthermore, the full potential of PSMA PET-CT has yet to be established.
