The peripheral blood smear of a patient shows features of thalassemia, also presented with anemia. Family history is also +ve. The investigation was done to establish the diagnosis is -
1) ESR estimation
2) Blood spherocyte estimation
3) Bone marrow aspiration
4) Hb-electrophoresis
General Pathology
Answer: 4
Hb-electrophoresis is the investigation done to establish the diagnosis of thalassemia, as it separates different hemoglobin types based on their charge.
Commonest type of Basal cell carcinoma is -
1. Ulcerated
2. Cystic
3. Morphoeic
4. Pigmented
Pathology
Answer: 1
1. Noduloulcerative Basal Cell Carcinoma: This is the most common subtype of
BCC, making up about 60-70% of all cases. It typically appears as a slowly
growing, round to oval, pearly or translucent nodule with a central ulceration
that may bleed or ooze. The borders of the lesion are often not well-defined and
may have a rolled, pearly edge with telangiectasias (small, dilated blood
vessels).
2. Cystic Basal Cell Carcinoma: This subtype presents as a round, dome-shaped
lesion with a cystic or fluid-filled center. It is less common than the
noduloulcerative type, and it may be mistaken for a benign cyst or epidermoid
cyst.
3. Morphoeic Basal Cell Carcinoma: Also known as sclerosing or morpheaform BCC,
this type is characterized by a slowly growing, ill-defined, firm, plaque-like
lesion that can infiltrate deeply into the skin. It may have a whitish, waxy
appearance with a scar-like texture. Morphoeic BCC tends to be more aggressive
and can be challenging to diagnose due to its subtlety.
4. Pigmented Basal Cell Carcinoma: This is a less common variant of BCC,
accounting for approximately 6-15% of cases. It presents with pigmentation in
the lesion, which can be brown, blue, or black. The presence of pigment can make
it look similar to melanoma, another type of skin cancer, so a biopsy is often
necessary to confirm the diagnosis.
Which of the following sexually transimitted is not of diseases either bacterial or chlamydial origin
1. Gonnorhoea
2. Syphilis
3. Molluscum contagiosum
4. Lymphogranuloma venereum
Oral Pathology
Answer: 3
Molluscum contagiosum is a viral infection caused by a poxvirus, not a bacterial or chlamydial infection. The other options (gonorrhea, syphilis, and lymphogranuloma venereum) are all caused by bacteria.
What phenomenon is responsible when a person sets off the metal detector at the airport, despite removing watch, belt buckle, and every other obvious source of metal?
1) Argyria
2) Gall stones
3) Hemochromatosis
4) Kidney stones
General Pathology Answer: 3
Hemochromatosis is a condition characterized by excessive iron accumulation in the body, which can lead to a false positive on metal detectors due to high iron levels in tissues.
Using "B" film, exposure is 1 R. What is the exposure when "D" film is used
1. 1 R
2. 1/2 R
3. 1/4 R
4. 1/8 R
Oral Pathology
Answer: 3
Using "B" film, exposure of 1 R will be reduced to 1/4 R when "D" film is used.
Recurrent ulcers occuring on gingival and palate are most probably
1) Aphthous ulcers
2) Herpes simplex
3) Koplick spots
4) Lesions of Behcet"s syndrome
Oral Pathology
Answer: 2
Recurrent ulcers on the gingiva and palate are most commonly associated with herpes simplex virus (HSV) infections. Herpes simplex can cause painful vesicular lesions that eventually ulcerate, leading to recurrent oral ulcers, particularly in the mucosal areas such as the gingiva and palate.
Aphthous ulcers (option 1) typically occur on non-keratinized mucosa and are not usually found on the gingiva. Koplick spots (option 3) are associated with measles and are not ulcers but rather small, bluish-white spots on the buccal mucosa. Behcet's syndrome (option 4) can cause oral ulcers, but they are often more widespread and associated with systemic symptoms. Therefore, the most probable cause of recurrent ulcers specifically on the gingiva and palate is herpes simplex.

1. High-protein diet
2. Tetracylines
3. Penicillins
4. Erythromycin
Oral Pathology
Answer: 2
Yellowish discoloration of teeth in children fed on tetracyclines is common.
