Key Clinical Message We present a patient catheterized for prostatic lesions who developed sepsis of urinary origin with a penile cavernosal abscess due to urethral injury caused by catheter ballooning. Urethral injury might lead to a life‐threatening penile abscess.

Key Clinical Message Octreotide is used in patients with insulinomas to treat hypoglycemia, and somatostatin receptor (SSTR) 2 expression is important for its efficacy. We report a case of insulinoma in a 50‐year‐old woman that responded to an octreotide test, showed accumulation in somatostatin scintigraphy, and was positive for SSTR2A on immunostaining.

Abstract Cushing's syndrome (CS) shows diverse signs such as centripetal obesity, moon face, and buffalo hump, which can complicate the diagnosis. Facial features including eyelid edema, as an underrecognized sign, can be diagnostic clues for an excess of corticoids in a CS patient.

Abstract Calcimimetic treatment has been reported to be effective for primary hyperparathyroidism (PHPT). Nine elderly PHPT patients who had been treated with calcimimetics were retrospectively analyzed. It was found that calcimimetics can reduce elevated serum calcium levels in elderly PHPT patients with low femoral DEXA %YAM and low urinary cAMP levels.

Abstract Although ascites leakage to the skin is the most frequent complication after abdominal paracentesis, leakage to the subcutaneous space has not been reported. Here, we report a subcutaneous effusion after paracentesis suggesting ascites leakage. We should be aware of this rare complication due to the potential risk of dissemination.

Abstract Autosomal‐dominant polycystic kidney disease (ADPKD) is rarely complicated by celiac artery dissection. Dissection of the aorta and its major branches should be carefully differentiated in ADPKD patients with acute‐onset abdominal pain.

Abstract Erdheim‐Chester disease (ECD) is a rare non‐Langerhans cell histiocytosis, involving multiple organs. We report a case of ECD with typical features of an orbital mass and "hairy kidneys," whose recognition can lead to early diagnosis and treatment.

Abstract We report a case of isolated adrenocorticotropin deficiency caused by pembrolizumab. This condition can be fatal, but its rarity causes under‐recognition. Oncologists should pay attention to adrenal insufficiency due to pembrolizumab.

Abstract Pseudoacromegaly is a condition characterized by acromegalic physical features without growth hormone excess, for which radiographic observation has seldom been reported. This is a rare case of pseudoacromegaly.

Abstract We report a patient with adrenal incidentaloma due to synchronous and isolated metastasis from lung cancer, which is a relatively rare condition. Close checkups for incidentaloma in oncologic patients are mandatory, leading to successful operation.

Abstract Renal cysts are detected in one third of acromegaly patients, especially in uncontrolled cases. Clinicians should pay attention to unexpected infection of enlarged renal cysts in acromegaly patients.
