A 20-year-old part-time college student comes to your clinic, complaining of growths on his penile shaft. They have been there for about 6 weeks and haven't gone away. In fact, he thinks there may be more now. He denies any pain with intercourse or urination. He has had three former partners and has been with his current girlfriend for 6 months. He says that because she is on the pill they don't use condoms. He denies any fever, weight loss, or night sweats. His past medical history is unremarkable. In addition to college, he works part-time for his father in construction. He is engaged to be married and has no children. His father is healthy, and his mother has hypothyroidism. On examination the young man appears healthy. His vital signs are unremarkable. On visualization of his penis you see several moist papules along all sides of his penile shaft and even two on the corona. He has been circumcised. On palpation of his inguinal region there is no inguinal lymphadenopathy. Which abnormality of the penis does this patient most likely have?

Correct Answer: A

Rationale: The patient in the case presented has multiple moist papules on the penile shaft and corona, which are classic features of condylomata acuminata, also known as genital warts. Condylomata acuminata are caused by the human papillomavirus (HPV) and are typically painless, unlike other conditions such as genital herpes or syphilitic chancre which may be associated with pain or tender sores. Given the patient's history of multiple sexual partners and lack of condom use with his current girlfriend, there is a higher likelihood of exposure to HPV. Condylomata acuminata can be treated with various options including topical agents, cryotherapy, or surgical removal, and it is important to address the potential risk of HPV transmission to sexual partners.

Correct Answer: A

Rationale: Acknowledging and taking responsibility for any part you may have played in provoking the patient's anger is important in effectively addressing the situation. By avoiding admission of your lateness, you may come across as dismissive of the patient's feelings and not addressing the issue at hand. It is essential to validate the patient's feelings and work towards finding a solution rather than avoiding the issue.

Correct Answer: D

Rationale: Since the patient, Susanne, has been experiencing headaches, muscle aches, and fatigue for the last 2 months, and a thorough history, examination, and laboratory workup have not revealed a definitive cause, the next step would be to screen for depression. Depression can present with physical symptoms such as headaches, muscle aches, and fatigue. It is important to consider mental health factors that could be contributing to Susanne's symptoms before proceeding with further referrals to specialists. Screening for depression would help in determining if psychological factors are playing a role in her physical symptoms.

Correct Answer: B

Rationale: The description of an oval, brown, slightly elevated lesion with a flat surface and rough, wartlike texture on palpation is characteristic of a seborrheic keratosis. Seborrheic keratoses are common benign skin growths that typically occur in older adults. They can vary in color, ranging from tan to dark brown, and often have a waxy or stuck-on appearance. The lesion described does not fit the typical characteristics of actinic keratosis, basal cell carcinoma, or squamous cell carcinoma.

Correct Answer: A

Rationale: The clinical presentation described in the scenario is consistent with benign prostatic hyperplasia (BPH). BPH is a non-cancerous enlargement of the prostate gland, typically seen in older males. The findings of a smooth, enlarged prostate on digital rectal examination without discrete masses, along with the absence of other alarming signs such as blood in the urine or on examination, make BPH the most likely diagnosis in this case.

Correct Answer: C

Rationale: The description of the patient's left shoulder pain, with a sharp catching pain and a sensation of something grating during overhead movements, in addition to tenderness just below the tip of the acromion in the area of tendon insertions, is suggestive of calcific tendinitis. Calcific tendinitis occurs when calcium deposits form within a tendon, most commonly affecting the rotator cuff tendons. This condition can cause pain, tenderness, and limited range of motion, particularly with certain movements like overhead reaching. The negative drop arm test, lack of limitation with shoulder shrug, absence of tenderness to palpation in the bicipital groove, and the patient not holding his arm close to his side help differentiate calcific tendinitis from other shoulder pathologies like rotator cuff tendinitis, rotator cuff tear, and bicipital tendinitis.

Correct Answer: C

Rationale: A "red flag" regarding patients presenting with a headache is their age being over 50. This is because new-onset or persistent headaches in individuals over 50 may raise concerns about underlying serious conditions such as temporal arteritis, brain tumor, or other vascular issues. It is important to thoroughly evaluate and consider these possibilities in older patients with headaches to ensure appropriate management and timely intervention.

Correct Answer: A

Rationale: Anisocoria refers to a condition where the pupils are of unequal size. Pathologic causes of anisocoria can include conditions such as Horner's syndrome. Horner's syndrome is a rare disorder caused by damage to the sympathetic nerves of the face and eye. Symptoms can include a constricted pupil (miosis), drooping of the upper eyelid (ptosis), and decreased sweating in the affected area. This results in anisocoria, where the affected pupil is smaller than the unaffected pupil. Other options listed (B-D) do not typically lead to pathologic anisocoria.

Correct Answer: A

Rationale: The most significant risk factor for breast cancer in the patient's personal and family history is having a first-degree relative with premenopausal breast cancer. This is because the age at which a family member was diagnosed with breast cancer can be indicative of potential genetic predispositions that may increase the patient's own risk of developing the disease. Women with a first-degree relative who was diagnosed with breast cancer before menopause (premenopausal) are at a higher risk themselves compared to those with a family history of postmenopausal breast cancer. In this case, the patient's mother had unilateral breast cancer in her 70s, which suggests a higher risk compared to postmenopausal breast cancer. Other factors such as early age at menarche or age at first live birth are also important in assessing breast cancer risk, but having a first-degree relative with premenopausal breast cancer is the most significant
