Patient: Male, 77 Final Diagnosis: Squamous cell carcinoma Symptoms: Epidermoid cyst Medication: — Clinical Procedure: Cyst excision Specialty: Plastic Surgery Objective: Rare co-existance of disease or pathology Background: Epidermoid cysts are the most common benign skin lesions that can occur anywhere on the body, and frequently occur on the face, scalp, neck, and trunk. Typically, patients are asymptomatic, and the lesions present as firm skin-colored nodules filled with keratinous or sebaceous materials that are formed by cystic expansion of the epidermal epithelium. Malignant transformation is rare in epidermoid cysts. Case Report: This is a case report of a 77-year-old male Caucasian patient who presented with an epidermoid cyst on the left parietal area. Due to high suspicion, the cyst was surgically excised and sent to pathology which resulted in discovery of malignant squamous cell carcinoma with unclear margins. Aimed at obtaining clear margins, a wide excision was performed, which revealed clean margins and absence of residual cancerous cells. The patient recovered well without major complications. Conclusions: Although the prevalence of epidermoid cysts is high, malignant transformation of epidermoid cysts into squamous cell carcinoma is rare. Due to its scarcity, the exact pathophysiology of malignant transformation is still poorly understood. The differential diagnosis should include the possibility of malignancy for highly suspicious lesions, and proper management guidelines should be established. Surgical resection should be the treatment of choice, and once removed, all surgically excised cysts should undergo pathologic evaluation. As clinicians, it is crucial to stay vigilant and have a low threshold for excision and thorough histological examination of specimens to allow early diagnosis and interventions which can significantly improve patient outcomes. Through the suggested guidelines, we hope to aid in better management and intervention in case of malignant transformation of epidermoid cysts.

Leptomeningeal carcinomatosis (LC) is a rare leptomeningeal spread of diffusely metastatic tumors. It occurs more commonly with hematologic tumors, less commonly with solid tumors, and is exceedingly rare in prostate cancer. Due to its scarcity, it has traditionally been difficult to diagnose LC but advancement of MRI has helped considerably. However, even with technological improvements, pre-mortem diagnosis of LC remains difficult and controversial. Our case is a 71-year-old male with prostate cancer with bone metastases who presented to our facility with altered mental status (AMS), lower extremity weakness, and worsening diarrhea. The diarrhea was responsive to antibiotic therapy, but his AMS did not resolve. A head CT without contrast was negative but follow-up brain MRI revealed leptomeningeal enhancement highly suggestive of LC. Cerebrospinal fluid (CSF) cytology results were negative and other CSF studies were inconclusive. Although further studies were planned, the patient continued to deteriorate, and the family elected to withdraw care. He passed away without beginning treatment for the LC. Despite advances in cancer therapies, LC remains difficult to diagnose and treat. Imaging may be suggestive of the condition but the confirmatory tests such as repeated CSF cytology or meningeal biopsy are not only invasive but also usually occur postmortem. Additional methods of CSF testing have been studied to evaluate their role in accurately diagnosing LC but low specificity for LC has somewhat limited their use. Although treatment options are mainly palliative in nature, prompt recognition and early treatment could grant valuable time for patients and families.

HighlightsMalignant phyllodes tumor is not very well-studied due to its scarcity and subtle clinical presentation.The malignancy risk at BIRADS 3 with fibroadenoma after age 40 is low which prompts reconsideration of invasive maneuvers.Early-stage malignant phyllodes tumor can be successfully treated only with lumpectomy without any adjunctive therapy.As with any tumors, early detection is key to a successful treatment and prevention of unnecessary invasive procedures.

Although the overall rate of colorectal cancer (CRC) has remained stable, studies have shown an increase in the rate of CRC in young patients (<50) nationwide. We hypothesize that the rectal cancer (RC) rate in young people has increased in rural Appalachia. The goal is to provide insight into the future of RC epidemiology in underserved populations. This Institutional Review Board–approved retrospective study evaluated RC patients diagnosed in 2003 to 2016, and compared the ratio of early-onset RC to the state and national ratios using West Virginia State Cancer Registry, North American Association of Central Cancer Registries (NAACCR) and Surveillance, Epidemiology, and End Results Program Database. Demographics include age, gender, ethnicity, and county. We also evaluated cancer stage, family history, and comorbidities, including body mass index, smoking, and alcohol history. The rate of early-onset RC in our area is 1.5 times higher than the national rates. In our population, 100 per cent of patients were white with an equal gender distribution. Young patients with RC were noted to be more overweight than national rates. Young RC patients are more likely to have a first- or second-degree relative with cancer diagnosis. Smoking was strongly associated with young RC. Compared with national statistics, a higher proportion of young patients had Stage 1 or 2 disease which correlated with better survival. The rate of early-onset RC in the Tristate Appalachian area in West Virginia is higher than the national rate with risk factors including white ethnicity, obesity, diabetes mellitus, smoking, family history, and history of pelvic surgeries. It warrants further investigation and discussion of current CRC screening guidelines that begin at age 50.
