Introduction: The aims of this study are to define the coracoid process anatomy in a Malaysian population, carried out on patients in Hospital Serdang with specific emphasis on the dimension of the base of coracoid process which is important in coraco-acromial (CC) ligament reconstruction, to define the average amount of bone available for use in coracoid transfer, and to compare the size of coracoid process based on gender and race, and with findings in previous studies. Materials and Methods: Fifteen pairs of computed tomography (CT) based 3-dimensional models of shoulders of patients aged between 20 to 60 years old were examined. The mean dimensions of coracoid were measured and compared with regards to gender and race. The data were also compared to previously published studies. Results: The mean length of the coracoid process was 37.94 ± 4.30 mm. Male subjects were found to have larger-sized coracoids in all dimensions as compared to female subjects. The mean tip of coracoid dimension overall was 19.99 + 1.93mm length x 10.03 + 1.48mm height x 11.63 + 2.12mm width. The mean base of coracoid dimension was 18.96 + 3.71mm length x 13.84 + 1.76mm width. No significant differences were observed with regards to racial denomination. The overall coracoid size measurements were found to be smaller compared to previous studies done on the Western population. Conclusion: This study may suggest that Malaysians have smaller coracoid dimension compared to Caucasians. The findings further suggest that the incidence of coracoid fracture and implants pull out in Malaysian subjects may be higher.

Epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. It is usually small, asymptomatic, and solitary in lesion. When the size is greater than 5 cm, it is classified as a giant epidermal cyst. If the size is big, it may sometimes mimic a soft tissue sarcoma, hence requiring further evaluation with imaging or histopathological studies. We report a case series of two patients whom presented with a huge swelling at different body regions, involving gluteal and chest. Both patients underwent different modes of imaging to delineate the anatomical extent of the lesion. Excision biopsy was done and the histopathological report confirmed epidermal cyst with no malignancy. The purpose of this case series is to describe the rare occurrence of giant epidermal cyst and to elaborate the methods of approach to arrive at the diagnosis.
