Of the four subtypes of cutaneous melanoma, acral lentiginous melanoma (ALM) is atypical in its presentation. ALM is a rare melanoma subtype that presents on the volar surfaces of the hand and foot. The difficulty of making an early diagnosis of ALM is highlighted by the case seen in our institution.

Fascin overexpression has been associated with epithelial to mesenchymal transition and correlates with progression and unfavourable prognosis in breast carcinoma.
Objective: To evaluate fascin expression by immunohistochemistry and correlate the expression pattern with clinicopathological parameters in breast cancer in African-American (AA) women, in whom triple negative breast cancer (TNBC), an aggressive subtype, is more prevalent.
Introduction: Due to increased awareness of breast cancer resulting in early detection, there is a decreased incidence nationwide of late-stage breast cancer, including that which presents with skin involvement (T4b).
Methods: A retrospective analysis of a 10-month period from August 2007 to May 2008 at Howard University Hospital (HUH), Washington, DC, revealed 12 patients diagnosed with T4b breast cancer and compared to similarly staged patients in the Surveillance, Epidemiology, and End Results (SEER) database. Finally, a logistic regression for the likelihood of T4b diagnosis was performed patients in the SEER database.
Hypothesis: Extended surgical resection (ESR) may improve survival in patients with early-stage primary gallbladder cancer.
Design: Retrospective analysis of findings in the Surveillance, Epidemiology, and End Results (SEER) database.
Setting: Academic research.
Background: Accidental traumatic injury is the number 1 cause of morbidity and mortality in the pediatric population. In this study, we aim to prove that certain pediatric patients can be treated with good outcomes at an adult level 1 trauma center.
Methods: Retrospective analysis using the Howard University Hospital trauma registry identified 71 patients treated at Howard University Hospital between the ages of 1 and 17 years old.
Background: Much debate exists over the significance of the number of lymph nodes (LN) examined after colon resection.
Materials And Methods: The Surveillance, Epidemiology and End Results (SEER) database was queried for patients who presented with colonic adenocarcinoma. Multiple Cox proportional hazard regressions were run using successive LN cut-offs (6-26), first controlling for and then stratifying by T-stage.
Randomized clinical trials have not shown survival differences between breast cancer patients who undergo breast-conserving surgery and those who undergo modified radical mastectomy (MRM). Recent studies however, have suggested that these randomized clinical trials findings may not be representative of the entire population or the nature of current patient care. A retrospective analysis of female invasive breast cancer patients who underwent surgery in the Surveillance, Epidemiology, and End Results database (1990-2003) was performed.

Method: The Surveillance, Epidemiology and End Results database was used to run an adjusted logistic regression for the receipt of cancer-directed treatment modalities.
Results: Of patients with specific surgical procedures recorded (n = 2,104), 86.
Background: Emergency department thoracotomy (EDT) is a procedure used in an attempt to save lives of patients in extremis. This study aims to determine predictors of survival and futility by proposing a scoring scale that measures cardiac instability and its use in predicting survival of victims of penetrating trauma undergoing EDT.
Methods: This retrospective study analyzes patients who underwent EDT during a 45-month period at Howard University Hospital, Washington, DC.
The Gail model has been used to predict invasive breast cancer risk in women using risk factors of age, age at menarche, age at first live birth, number of first-degree relatives with breast cancer, and number of previous benign breast biopsies. However, this model underestimates breast cancer risk in African-American women. The Contraceptive and Reproductive Experience (CARE) model has been developed to replace the Gail model in predicting breast cancer risk in African-American women.

We subsequently performed a formal assessment of the academic needs of West African surgeons to plan for future courses, and hypothesized that they would differ from the goals of the U.S.

Carcinoids involving the ampulla of Vater are rare lesions that may produce painless jaundice. The published data indicate that these tumors, in contrast to their midgut counterparts, metastasize in approximately half of cases irrespective of primary tumor size. Therefore, radical excision in the form of pancreaticoduodenectomy is recommended regardless of tumor size.
View Article and Find Full Text PDFPurpose: Pancreatic adenocarcinoma is currently the fourth leading cause of cancer death in the United States, and most pancreatic cancers develop locally advanced disease or metastasis at the time of diagnosis. The mechanisms by which it invades and metastasizes are not known.
Experimental Design: To identify the genes involved in pancreatic cancer metastasis, we analyzed the gene expression profiles between highly metastatic Colo357L3.
