Androgens cause acne. Testosterone is a better answer than Androstanediol b/c the Testosterone is associated with puberty, Androstanediol is more associated with the adrenal glands.

meningitis  I chose Testosterone but I almost chose GnRH because it is surged when starting puberty and therefore increases everything downstream. +1  
temmy  When answering the question, i thought to myself that if GnRH is correct, LH will be too cos GnRH stimulates the Leydig cells via LH to release testosterone. That left testosterone as the best answer because it had the most direct effect. +1  
goaiable  GnRH and LH are increased in a pulsatile fashion at the onset of puberty, so idk if that constitutes as the "rapid increase" that this question is asking for. Tripped me up also. +

I think metastasis was the best option here because there are multiple malignant neoplasms... primary cancers tend to start as a single mass in the tissue of origin. In the lung, metastases are more common than primary neoplasms.

dbg  I seriously could not figure out whether those white opacities were actual lesions or reflections from the actual picture (flash light) ... mind went all the way maybe this is the shiny pleura so they're going after mesothelioma. smh +1  
dbg  shiny pleura with tiiiiny granulations if you look closely. but obviously was far off +  
et-tu-bromocriptine  "Multiple cannonball lesions" is indicative of a metastatic cancer. I think if they were leaning towards a mesothelioma, they'd show the border/edge of the lung ensheathed by a malignant neoplasm (see image): https://library.med.utah.edu/WebPath/jpeg1/LUNG081.jpg +1  
bullshitusmle  guys something I learned from NBMEs is that if there is a clinical vignette dont even look at the images they give you ,they are all useless and time-consuming +  
goaiable  The way i narrowed it down was that the patient had signs of weight loss since three months whereas her cough developed recently (3 weeks). If the cancer arose in the lung then I think the cough or other pulmonary symptoms should emerge earlier. +
