Topic 4: Perforator flap
This is a new subgroup of the axial flap in which tissue is isolated on small perforating vessels that run from more major blood vessels to supply the surface.
Topic 5: Adipose necrosis of Breast
Adipose necrosis can mimic breast cancer in its clinical and mammographic presentation
Adipose Necrosis or Fat Necrosis can follow breast operations as is in this case of reduction Mammoplasty. Adipose necrosis can mimic breast cancer in its clinical and mammographic presentation. Fat necrosis is uncommon due to Physical trauma or Ischemia resulting from stretching and narrowing of arteries in pendulous breasts may be a factor.
Topic 6: Medullary Cancer Thyroid

Topic 8: Hamann’s Sign is seen in… Oesophageal perforation

Shock and emphysemas are more frequent after perforation of the thoracic Oesophagus then after perforation of the cervical Oesophagus. Emphysema around pericardium may produce mediastinal crunch called a Hamanns Sign. Chest radiography and Gastrografin swallow study, (followed by barium study if the gastrografin swallow is negative) is diagnostic in most cases.
Topic 9: Oliguria, Chest Pain with Dyspnea may be seen along with petechiae on chest in………..Which Type of Embolism
