A patient presents with a pruritic, annular rash with central clearing and a raised, scaly border. The lesions have a tendency to spread outward in a centrifugal pattern. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.

Correct Answer: A

Rationale: The description of multiple flesh-colored papular lesions with a central dell that tend to bleed upon minor trauma and have been increasing in number over time is characteristic of basal cell carcinoma. Basal cell carcinoma is the most common type of skin cancer and typically presents as pearly or flesh-colored papules with telangiectasias (tiny blood vessels) and a characteristic central dell or ulceration. This type of skin cancer often occurs on sun-exposed areas like the face and trunk and can manifest as slow-growing lesions that may bleed easily with minor trauma. In contrast, squamous cell carcinoma typically presents as a scaly or crusted lesion, seborrheic keratosis is a benign skin growth with a waxy, stuck-on appearance, and actinic keratosis is a precancerous lesion characterized by rough, scaly patches on sun-exposed areas.

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: A

Rationale: The patient's presentation of recurrent episodes of postnasal drip, chronic cough, halitosis, and foul-smelling, yellowish discharge from the middle meatus is highly suggestive of chronic rhinosinusitis. The presence of nasal polyps further supports this diagnosis. Chronic rhinosinusitis with nasal polyps is characterized by inflammation of the paranasal sinuses, leading to symptoms such as nasal congestion, postnasal drip, cough, and a reduced sense of smell. The yellowish discharge and foul odor are typical findings in cases of chronic rhinosinusitis with secondary bacterial infection. Nasal endoscopy may reveal edematous nasal mucosa and polyps obstructing the middle meatus, contributing to the symptoms described by the patient. Management typically involves a combination of medical therapies such as intranasal corticosteroids, saline irrigation, and antibiotics, and in some cases, surgical intervention

Correct Answer: A

Rationale: The presentation described in the question is classic for anterior uveitis. Anterior uveitis is an inflammatory condition affecting the iris and ciliary body and is characterized by redness, pain, and photophobia. Slit-lamp examination typically reveals ciliary injection (redness around the iris), corneal edema, and a mid-dilated pupil with a fixed reaction to light due to inflammation causing spasm of the iris muscles. Acute angle-closure glaucoma would present with similar symptoms but would also have increased intraocular pressure, which is not mentioned in the presentation. Endophthalmitis is an infection of the intraocular cavities and would typically present with more severe symptoms, such as severe pain, vision loss, and presence of pus in the eye. Corneal abrasion would present with pain, foreign body sensation, and possibly tearing but would not cause ciliary injection or fixed pupil reaction as
