Skin Metastasis of Renal Cell Carcinoma: A Case Report

Scalp Metastasis From Renal Cell Carcinoma: A Rare Case With Rapid Progression

Renal cell carcinoma (RCC) is a common renal malignancy that frequently metastasizes, though cutaneous metastasis, particularly to the scalp, is rare and generally indicates a poor prognosis. We report a case of scalp metastasis from RCC in a 69-year-old man who presented with unexplained weight loss and painless hematuria. Imaging revealed a 12-cm renal mass with adrenal, pulmonary, and scalp metastases. The patient's condition rapidly deteriorated, and he died one month after the presentation. Hematogenous spread through Batson's plexus might be the primary mechanism of RCC dissemination to the scalp. While targeted therapies have improved the management of metastatic RCC, the prognosis for patients with skin metastases remains poor.

Rapid metachronous bladder metastasis of type 2 papillary renal cell carcinoma

Renal cell carcinoma (RCC) frequently spreads to distant organs like the lung, lymph nodes, bone, and liver. However, there have been some reports of RCC bladder metastasis. We present a case of a 61-year-old man presented with total painless gross hematuria. The patient had a history of right radical nephrectomy for papillary (type 2) RCC, high-grade, pT3a with negative surgical margins. There was no evidence of metastases on 6-month surveillance CT. After one-year post-operation, at this current admission, the cystoscopy discovered a solid bladder mass away from the trigone in the right lateral bladder wall. The resected bladder mass was metastatic papillary RCC with PAX-8 positive but GATA-3 negative on immunostaining. A positron emission tomography scan confirmed multiple lung, liver, and osseous metastases. This case report can highlight the importance of having bladder metastasis in RCC mind, although rare, and may necessitate the surveillance measures like urine analysis at more frequent interval and CT Urography instead of regular CT to detect the RCC metastatic bladder cancer at early stage.

Metastatic Renal Cell Carcinoma to the Scalp: A Case Report With Review of Literature

Renal cell carcinoma (RCC) is the most common type of renal neoplasm. It accounts for 3% of solid tumors in adults and mostly affects men with the peak incidence between the fifth and seventh decades. It metastasizes mainly through the hematogenous spread, and the lung is the most common site of metastasis followed by bone, lymph node, liver, brain, and adrenal glands. Skin metastasis is extremely rare and accounts for <7% of RCC metastases, with the scalp and face being the most reported sites. Skin metastases are usually diagnosed at a later stage of the disease, commonly post-nephrectomy, and are regarded as a poor prognostic factor. Here we report a case of a 54-year-old male who presented with a red, pedunculated, bleeding, and nontender scalp lesion (2x2cm in size) found on the right parietal area. with a history of left radical nephrectomy and adjuvant chemotherapy for clear cell RCC 17 years ago, as well as laminectomy and radiotherapy for bone metastases in C5 and C6 in 2015. After surgical excision of the scalp lesion, histology revealed metastatic clear cell RCC. The patient was doing well post-surgical excision and was referred back to oncology where palliative care and supportive treatment were initiated. In the span of five months post-resection, he developed several conditions where his health further deteriorated. He was announced dead in September 2022 due to cardiac arrest. This case highlights the occurrence of scalp metastases long after the surgical resection of RCC.

A Rare Case of Trichilemmal Carcinoma: Histology and Management

Trichilemmal carcinoma (TC) is a rare cutaneous tumor thought to be derived from the follicular outer root sheath (ORS). It often manifests as a nondescript skin-colored or pink papule on the hair-bearing, sun-exposed anatomic sites of elderly patients. Trichilemmal carcinoma shows many histologic features reminiscent of follicular ORS-notably, its glycogen-rich clear cells, trichilemmal keratinization, and similar immunostaining profile. Historically, it has been described as following a relatively indolent clinical course, but cases of recurrence, local aggression, and distant metastases have recently been elucidated. Here, we report the case of a 66-year-old male patient who presented with an asymptomatic, erythematous plaque on his neck; biopsy confirmed a diagnosis of TC. The patient deferred Mohs micrographic surgery in favor of wide local excision and was treated successfully with 3-mm margins. Salient histopathologic features, treatment modalities, and management recommendations are discussed.

Isolated temporalis muscle metastasis of renal cell carcinoma

Isolated head and neck metastasis of renal cell carcinoma (RCC) is relatively rare and metastasis to the temple area is very rare. Here, we present the case of a 51-year-old man who was diagnosed with RCC 2 years earlier and had a contralateral metastatic temple area lesion. The patient who was diagnosed with renal cell cancer and underwent a nephrectomy 2 years ago was referred to the plastic surgery department for a temple mass on the contralateral side. In the operative field, the mass was located in the temporalis muscle with a red-to-purple protruding shape. Biopsy of the mass revealed a metastatic RCC lesion. Computed tomography imaging showed a lobulated, contoured enhancing lesion. Positron emission tomography/computed tomography imaging showed high-fluorodeoxyglucose uptake in the right temporalis muscle. The patient underwent wide excision of the metastatic RCC including the temporalis muscle at the plastic surgery department. Skeletal muscle metastasis of head and neck lesions is extremely rare in RCC. Isolated contralateral temporalis muscle metastasis in RCC has not been previously reported in the literature. If a patient has a history of malignant cancer, plastic surgeons should always consider metastatic lesions of head and neck tumors. Because of its high metastatic ability and poor prognosis, it is very important to keep this case in mind.

Latent distant metastasis of renal cell carcinoma to skin: A case report

Renal cell carcinoma (RCC) is known to recur decades after nephrectomy; however, isolated cutaneous metastasis is rare. Previous clinical history plays vital role. Newly occurring skin lesions in follow-through patients of RCC should be carefully evaluated, and possibility of its metastasis should be acknowledged. Disease-free survival postmetastasectomy is possible.
