A patient presents with multiple, dome-shaped, translucent papules with central umbilication on the face and trunk. The lesions are asymptomatic and have been gradually increasing in number. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: B

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple dome-shaped, translucent papules with central umbilication on the face and trunk. The lesions are usually asymptomatic but can be itchy. Molluscum contagiosum is a common infection in children but can also occur in adults, especially those who are immunocompromised. The lesions can gradually increase in number over time. Basal cell carcinoma, sebaceous hyperplasia, and keratoacanthoma do not typically present with the characteristic features of molluscum contagiosum.

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

Correct Answer: A

Rationale: The presentation described in the question is characteristic of anterior uveitis. Anterior uveitis is inflammation of the iris and ciliary body in the eye. Patients typically present with symptoms such as redness, pain, and photophobia. Slit-lamp examination findings include ciliary injection (redness and engorgement of blood vessels in the ciliary body), corneal edema (swelling of the cornea), and a mid-dilated pupil with a fixed reaction to light due to involvement of the iris muscles. These features differentiate anterior uveitis from other conditions. Treatment of anterior uveitis may involve topical steroids and cycloplegics to reduce inflammation and alleviate symptoms.
