The faculty member explains fungal skin diseases to a group of students. Which are the common types of this disorder?(Select all that apply.)

Correct Answer: D

Rationale: The correct answer is D: Tinea manus. Tinea manus refers to fungal infections on the hands. The other choices, A, B, and C, refer to fungal infections on the scalp, body, and groin respectively. Therefore, D is the correct answer as it pertains to fungal skin diseases affecting the hands specifically.

Correct Answer: C

Rationale: The correct answer is C because lindane shampoo should be applied to dry hair and then lathered with a small amount of water. This allows for better penetration of the medication into the hair and scalp to effectively treat pediculosis capitis. Washing the hair with an antimicrobial shampoo prior to lindane (choice A) is unnecessary and may reduce the efficacy of lindane. Scrubbing the head for 2 minutes before removing lindane (choice B) can also lead to inadequate treatment. Using lindane shampoo daily for a week (choice D) is incorrect as lindane should not be used daily due to its potential toxicity.

Correct Answer: C

Rationale: The correct answer is C because seborrhoeic keratosis often appears greasy due to the overproduction of sebum. This is a characteristic feature of this benign skin lesion. Choice A is incorrect as seborrhoeic keratosis typically occurs in older individuals, not teenagers. Choice B is incorrect as seborrhoeic keratosis is usually raised and has a waxy, stuck-on appearance, rather than flat. Choice D is incorrect as seborrhoeic keratosis is not a squamous cell papilloma, but rather a benign growth of keratinocytes.

Correct Answer: B

Rationale: The correct answer is B because there are indeed three types of neurofibromatosis: NF1, NF2, and schwannomatosis. NF1 and schwannomatosis have autosomal dominant inheritance, while NF2 has autosomal dominant inheritance with variable penetrance. Choice A is incorrect because types of neurofibromatosis do not have autosomal recessive inheritance. Choice C is incorrect because von Recklinghausen's disease is synonymous with neurofibromatosis type 1, not type 2. Choice D is incorrect because cutaneous lesions in neurofibromatosis are typically not painful.

Correct Answer: A

Rationale: Dermatoscopy refers to the examination of skin lesions using a dermatoscope, a tool that magnifies and illuminates the skin. This technique helps in analyzing the structures and patterns within the skin to aid in diagnosing various skin conditions. Choice A is correct because it accurately describes the process of dermatoscopy. Choice B is incorrect as it involves both examination and biopsy, not just examination. Choice C is incorrect as dermatoscopy does not involve removal of skin lesions. Choice D is incorrect as debridement refers to the removal of dead or damaged tissue, not the examination of skin lesions.
