A young man feels something in his scrotum and comes to you for clarification. On your examination, you note what feels like a "bag of worms" in the left scrotum, superior to the testicles. Which of the following is most likely?

Correct Answer: B

Rationale: A varicocele is a common cause of a "bag of worms" feeling in the scrotum. It occurs due to the dilation of the veins within the spermatic cord, leading to a palpable mass above the testicle. Varicoceles are more commonly found on the left side due to the anatomy of the left testicular vein, which drains into the left renal vein at a right angle, making it more susceptible to increased pressure and dilation.

Correct Answer: C

Rationale: The presence of an irregular, asymmetric, hard nodule on the posterior surface of the prostate detected during digital rectal examination raises suspicion for prostate cancer. Prostate cancer commonly presents with nodules or indurations on the prostate gland during physical examination. Other findings, such as no inflammation, masses, or fissures in the anus and normal examinations of the scrotum and penis, further support the likelihood of prostate cancer as the most probable diagnosis in this case. Additional laboratory results, including prostate-specific antigen (PSA) levels, can help confirm the diagnosis. Both benign prostatic hyperplasia (BPH) and prostatitis typically present with different symptoms than those described in the scenario, making prostate cancer the most likely disorder based on the provided information. Anorectal cancer is less likely given the absence of findings indicating involvement of the anus or rectum in this case.

Correct Answer: A

Rationale: Rectal prolapse occurs when the rectum protrudes through the anus. It typically appears as a moist, pink mass that protrudes outside the body. The prolapse is usually painless and can be seen and felt by the patient or the examiner. It is commonly seen in elderly individuals, especially women, and those with conditions like chronic constipation, pelvic floor weakness, or dementia. On the other hand, external hemorrhoids are swollen veins located around the anus, usually painful and may cause bleeding. Perianal fistula is an abnormal tunnel-like connection between the skin near the anus and the rectum, which can cause pain and discharge. Prolapsed internal hemorrhoids are internal hemorrhoids that have descended outside the anal canal and may require manual reduction. Given the symptoms described in the scenario - a moist pink mass protruding from the anus that is nontender and soft without bleeding - the most likely diagnosis is rectal prol

Correct Answer: B

Rationale: The scenario described suggests that Ray experiences pain only when actively lifting his arm over his head, which indicates the issue is likely originating from structures outside of the joint itself. When the shoulder is moved passively (moved by an external force), there is full range of motion without pain, suggesting that the limitation and pain occur due to muscles, tendons, or ligaments surrounding the joint rather than within the joint itself. In this case, the joint disease is likely to be extra-articular, involving structures such as muscles or tendons rather than being articular in nature.

Correct Answer: D

Rationale: Following a severe rotator cuff tear, it typically takes around 2-3 months for muscular atrophy to develop with increased prominence of the scapular spine. This is due to disuse of the affected shoulder muscles leading to muscle wasting and changes in the bony structures around the shoulder blade. Over time, the lack of muscle activity causes the shoulder blade to become more prominent and noticeable, which can result in altered sensations during activities like hugging. The gradual onset of these changes aligns with the timeline provided in the question, where the wife started to feel discomfort in her husband's left shoulder blade after the recent severe rotator cuff tear.
