Cutaneous metastasis from vulvar squamous cell carcinoma: a rare occurrence that should not be forgotten

Rare phalanges soft tissue and bony metastasis in vulvar squamous cell carcinoma: Case report

Vulvar cancer accounts for 0.3 % of new cancer cases within the Unites States. Metastatic vulvar cancer with disease beyond the pelvis is rare and has a poor prognosis. Data on primary treatment including systemic treatments for distant metastatic vulvar disease is limited due to rarity and lack of clinical trials. The purpose of this article is to present an atypical presentation of recurrent vulvar squamous cell carcinoma with metastasis to phalanges soft tissue and bone, clavicle and to the lungs and intracranial space.

Current Surgical Therapy of Locally Advanced cSCC: From Patient Selection to Microsurgical Tissue Transplant. Review

Among the non-melanoma skin cancers (NMSC) the squamous cell carcinoma (SCC) is one of the most challenging for the surgeon. Local aggressiveness and a tendency to metastasize to regional lymph nodes characterize the biologic behavior. The variants locally advanced and metastatic require wide excision and node dissection. Such procedures can be extremely detrimental for patients. The limit of the surgery can be safely pushed forward with a multidisciplinary approach. The concept of skin oncoplastic surgery, the ablative procedures and the reconstructive options (skin graft, pedicled flap, microsurgical free flap) are discussed together with a literature review.

Assessment of TSPAN Expression Profile and Their Role in the VSCC Prognosis

The role and prognostic value of tetraspanins (TSPANs) in vulvar squamous cell carcinoma (VSCC) remain poorly understood. We sought to primarily determine, at both the molecular and tissue level, the expression profile of the TSPANs CD9, CD63, CD81, and CD82 in archived VSCC samples (n = 117) and further investigate their clinical relevance as prognostic markers. Our studies led us to identify CD63 as the most highly expressed TSPAN, at the gene and protein levels. Multicomparison studies also revealed that the expression of CD9 was associated with tumor size, whereas CD63 upregulation was associated with histological diagnosis and vascular invasion. Moreover, low expression of CD81 and CD82 was associated with worse prognosis. To determine the role of TSPANs in VSCC at the cellular level, we assessed the mRNA levels of CD63 and CD82 in established metastatic (SW962) and non-metastatic (SW954) VSCC human cell lines. CD82 was found to be downregulated in SW962 cells, thus supporting its metastasis suppressor role. However, CD63 was significantly upregulated in both cell lines. Silencing of CD63 by siRNA led to a significant decrease in proliferation of both SW954 and SW962. Furthermore, in SW962 particularly, CD63-siRNA also remarkably inhibited cell migration. Altogether, our data suggest that the differential expression of TSPANs represents an important feature for prognosis of VSCC patients and indicates that CD63 and CD82 are likely potential therapeutic targets in VSCC.

Vulvar Cancer with Cutaneous and Breast Metastases

Vulvar cancer accounts for about 5% of cancer of female genitalia. It may initially present as benign symptoms resulting in potential delay in diagnosis. Few cases of distant metastases to skin or breast have been reported. We present the case of a 76-year-old female with possible delay in diagnosis of her squamous cell carcinoma of vulva. After 4 months of the diagnosis, she presented with concurrent cutaneous and breast metastases.

A Case of Stage I Vulvar Squamous Cell Carcinoma with Early Relapse and Rapid Disease Progression

Squamous cell carcinoma (SCC) is the most common subtype of vulvar cancer. Locoregional surgery is often curative when the tumor is diagnosed at an early stage. However, the disease can unexpectedly evolve with a dismal prognosis even after an early diagnosis. We report a case of a woman who experienced a rapid, chemorefractory tumor progression after surgery for stage IB vulvar SCC.
