Intestinal malrotations are associated with various anatomical anomalies. We report a unique case wherein the
caecum was located in the right lumbar region instead of the right iliac fossa. The ileo-caecal junction was also
placed higher up. The appendix was ‘uncinate’ shaped, highly coiled and retroperitoneal with the absence of mesoappendix.
Both, the caecum and appendix were supplied by ascending branch of the ileocolic artery instead of the
descending branch. Further, we also observed that the ascending colon was very short and sub-hepatic in position.
Such type of variations is of clinical and surgical importance in diagnosis and treatment of appendicitis.

Vascular variations in the neck region are not uncommon. Knowledge of incidence of morphological variations in
the course and branching of the carotid arteries is important for radiological interpretation and surgical correction
when they are symptomatic. Internal carotid artery (ICA) is known to show elongation in its extra cranial course.
Previous studies have demonstrated the incidence and clinical symptoms of this morphological entity. However, the
occurrence of elongation and looping of the external carotid artery (ECA) is seldom reported in the literature. During
regular dissections, we came across a rare case of unilateral morphological variation of both ECA and ICA, in a male
cadaver aged about 55 years. ICA presented a curved course with convexity directed posteriorly, at the level of the
C2-C3 vertebrae. ECA presented a pronounced kinking or coiling, one inch below the level of the angle of the
mandible. In addition, a linguo-facial trunk arising from the ECA also presented a pronounced kinking throughout its
entire length.

Knowledge of anatomic variants of veins in the arm and axilla play a key role in planning of successful venous
access. Possible anatomic variants of axillary vein, brachial vein and basilic vein and their clinical implications have
been well described in the literature. We report a rare case of formation of a short axillary vein associated with
complex venous communications between the basilic and brachial veins forming a venous ladder in the axilla, in
formalin embalmed male cadaver. Axillary vein was formed in the upper part of the axilla by the fusion of basilic
vein and unpaired brachial vein, and it was about 3cm in length. The higher-up confluence of basilic and brachial
veins was also associated with presence of three communicating veins between the basilic and brachial veins in the
axilla. Knowledge of reported venous variations is very useful during preoperative venous mapping and also for
planning and execution of various surgical invasive procedures involving these veins.

The extensor digitorum brevis muscle (EDB) is a practical option for use as an island flap or free flap when reconstructing soft tissue defects in the ankle as well as in the entire lower limb. It is frequently used to correct crossover toe deformity and other painful toe disorders. We evaluated the morphometry of the EDB in 44 formalin-fixed limbs. Length and width of the muscles were measured. Surface area was calculated as the product of length and width of the muscle. The length of each tendon was also measured from its origin to the point of distal attachment. Presence of any additional tendons was noted. Mean length, width, and surface area of the muscle were 7.39+/-0.71 cm, 4.1+/-0.37 cm, and 30.5+/-4.78 cm2 on the right side and 7.2+/-0.84 cm, 3.9+/-0.37 cm, and 28.4+/-5.35 cm2 on the left side, respectively. Morphometry of the tendons revealed that the tendon of the great toe had the highest mean length (9.5 cm) and the tendon of the fourth toe had the lowest mean length (6.3 cm). Four of the limbs studied (9.09%) had only three tendons. Three of the limbs studied (6.81%) had five tendons, and in one exceptional case (2.27%), six tendons were detected. These observations have significant value and are applicable to plastic and orthopedic surgery.

Veins of the head and neck exhibiting anatomical variations or malformations are clinically significant. Anatomical variation in the external jugular vein is very common. However, anatomical variation in the retromandibular vein is rare. In this paper, we report a rare case of complete absence of the retromandibular vein. In the absence of the retromandibular vein, the maxillary vein divided into anterior and posterior divisions. The posterior division joined the superficial temporal vein to form an atypical external jugular vein, and the anterior division joined the facial vein to form an anonymous vein. In clinical practice, radiologists and surgeons use the retromandibular vein as a guide to expose the branches of the facial nerve during superficial parotidectomy. Therefore, absence of the retromandibular vein is a hurdle during this procedure and may affect the venous drainage pattern from the head and neck.
