Merkel cell carcinoma occurring in a black woman: a case report.

BACKGROUND: Merkel cell carcinoma is a rare, very aggressive neuroectodermal tumor of the skin. It is typically located on sun-exposed skin and frequently found in white men aged between 70 and 80 years. CASE PRESENTATION: We report a case of a 58-year-old black woman diagnosed with Merkel cell carcinoma of the posterior face of the right elbow. She had biopsy excision and was lost to follow-up. Four months later, she presented with recurrent disease on the inferior third of the right arm with three ipsilateral axillary lymph node metastases. Amputation of the right arm and ipsilateral axillary lymph node dissection were performed, followed by adjuvant radiotherapy. Six months later, the patient died as a result of respiratory failure caused by lung metastasis. To the best of our knowledge, no specific studies have been done comparing the course and the characteristics of Merkel cell carcinoma in white and black populations, and no similar case has been reported in the literature. CONCLUSIONS: The Merkel cell carcinoma is very rare in black people. As described elsewhere in the literature, our patient had a poor outcome despite radical management. To date, to the best of our knowledge, there has been no comparison of the prognosis of this tumor in white and black populations.

Extra-axial ependymoma of the cerebral convexity: A very rare intracranial adult tumor.

Background Ependymomas are rare adult tumors that originate from the ventricular system or the ependymal surface of the central canal. Extra-axial supratentorial ependymomas are extremely rare, and only five cases have been reported to date in the English literature. Case presentation A 46-year-old previously healthy male presented with a gradual painless loss of vision in the right eye. Cerebral MRI showed a right parietal-occipital lesion resembling an atypical meningioma. Surgical resection was performed, and immunohistochemical staining results concluded that it was a very uncommon location of a grade 3 ependymoma. Favorable outcome was observed one year after completion of postoperative radiotherapy. Conclusion Clinical and imaging aspects are misleading in rare brain tumors, and immunohistochemistry is essential to re-address diagnosis.

Associated factors with psychological distress in Moroccan breast cancer patients: A cross-sectional study.

OBJECTIVES: To estimate the prevalence of psychological distress (PD) in Moroccan breast cancer patients, and to determine clinical and social demographic factors associated with PD. METHODS: It was a cross-sectional study where we included all female breast cancer patients that did not have other malignancies. Judgment criteria were based on the Hospital Anxiety and Depression Scale (HADS), and the Distress Thermometer (DT). Threshold values of 15 and 3 were fixed to detect patients on PD by the HADS and the DT, respectively. We analyzed data by calculation of Cronbach's alpha coefficient for the reliability of measurements, and by simple and multiple logistic regressions. RESULTS: 446 women were enrolled. Cronbach's alpha coefficient was 0.801, 0.669 and 0.639 respectively for the HADS, HAD-A and HAD-D questionnaires. 120 patients (26.9%) had a HADS global score ≥15. HAD-A and HAD-D sub-scores were ≥11 in 25 (5.6%) and 30 (6.7%) patients respectively. In multivariate analysis, adjusted for the education level, marital status, taking analgesic and/or anxiolytic treatment, and current treatment type; we found that the occurrence of a distant metastasis [OR = 14.427 p < 0.001], lack of social family support [OR = 4.631 p < 0.001], living a difficult emotional [OR = 2533 p = 0.034] and/or financial [OR = 2.09 p = 0.037] situation, and younger (<50 years) age [OR = 2.398 p = 0.002], were independent associated factors with PD as assessed by the HADS. CONCLUSIONS: Social family support, emotional and financial difficulties should be investigated in all Moroccan breast cancer patients, especially among younger ones, in order to detect those at risk of PD and offer them appropriate support.

Sebaceous carcinoma of the parotid gland: a case report and review of the literature.

BACKGROUND: Sebaceous carcinoma is a rare malignancy primarily with aggressive growth affecting the cutaneous tissues of the periocular region. Sebaceous carcinoma of the parotid gland is exceedingly rare, with only 32 cases reported in the literature. Our case brings this total to 33. CASE PRESENTATION: We present a case of a 57-year-old Moroccan woman with a firm, painless, slowly enlarging swelling at her left parotid area, with normal overlying skin and no palpable neck nodes. Parotidectomy with facial nerve preservation was performed, and microscopic examination showed sebaceous carcinoma. Then, she underwent adjuvant radiotherapy. With a follow up of 20 months, head and neck computed tomography revealed no recurrence. CONCLUSIONS: The optimal treatment is unclear. With more cases reported, clinicopathological characteristics and histogenesis are increasingly understood. Therefore the treatment for this rare tumor continues to evolve.

Uterine cervix metastasis from a sigmoid adenocarcinoma: a rare presentation of an uncommon tumor.

Metastatic carcinoma to the uterine cervix from colorectal cancer, through haematogenous or lymphatic spread, is extremely rare. We report the case of a 59 year old woman in whom cervical metastasis was diagnosed after 13 months of follow-up for a sigmoid adenocarcinoma, confirmed by immunohistochemical study, with a review of the literature. This case illustrates that abnormal gynecologic symptoms can reveal a disease progression on patients who suffer colorectal cancer.
