The 'peau d'orange' appearance of the skin in breast cancer is due to:
सही उत्तर: ख) Lymphatic obstruction causing cutaneous oedema
Peau d'orange is skin oedema from blocked dermal lymphatics, with the skin tethered at the hair follicles. Infiltration and shortening of Cooper's ligaments causes skin dimpling instead.

The most common histological type of breast carcinoma is:

Gustatory sweating over the cheek after parotidectomy (Frey's syndrome) is caused by aberrant regeneration of fibres carried in the:
सही उत्तर: घ) Auriculotemporal nerve
Parasympathetic secretomotor fibres to the parotid travel in the auriculotemporal nerve. After surgery they regrow into sweat glands of the skin, so eating causes sweating. Injury to the great auricular nerve causes numbness of the ear lobe.

The most common tumour of the salivary glands is:
सही उत्तर: ग) Pleomorphic adenoma

सही उत्तर: ख) Anterior border of the sternocleidomastoid at the junction of its upper and middle thirds

A cystic neck swelling in the midline that moves upward on protrusion of the tongue is most likely a:
सही उत्तर: क) Thyroglossal cyst
A thyroglossal cyst is attached to the hyoid and the remnant of the thyroglossal tract, so it moves on swallowing and on protruding the tongue. It is treated by Sistrunk's operation, which includes removing the central part of the hyoid.

The most likely cause of tingling around the mouth and carpopedal spasm on the second day after total thyroidectomy is:
सही उत्तर: घ) Hypocalcaemia due to parathyroid injury or devascularisation
Injury to or loss of blood supply to the parathyroids causes hypocalcaemia, with Chvostek's and Trousseau's signs. Thyroid storm presents with fever, tachycardia and agitation instead.

Follicular carcinoma of the thyroid characteristically spreads by:
सही उत्तर: ग) Haematogenous route to bone and lung
Follicular carcinoma invades blood vessels and spreads by the bloodstream to bone and lung. Papillary carcinoma typically spreads through lymphatics to the cervical nodes.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Medullary carcinoma of the thyroid arises from:
सही उत्तर: ख) Parafollicular C cells
Medullary carcinoma arises from calcitonin-secreting parafollicular C cells, so calcitonin is its tumour marker. It may be familial (MEN 2, RET mutation). Papillary and follicular cancers arise from follicular cells.
