Neonatal adrenal hemorrhage (NAH) is rare and is found in only 0.2% of newborns. Scrotal hematoma (SH) in newborns is also rare. NAH associated with SH is extremely rare, with only 29 cases reported in the literature. Herein, we report a baby boy who presented with SH; after ultrasonography examinations, the diagnosis of NAH associated with SH was made. He received conservative treatment only. From our experience and that of others, appropriate integration of clinical information, physical examination and the results of abdominal and scrotal ultrasonography can achieve the accurate diagnosis of NAH associated with SH. This association allows conservative treatment that avoids unnecessary surgical exploration.

Extramammary Paget's disease (EMPD) is a rare cutaneous carcinoma of epidermal origin. The diagnosis is frequently delayed, and the disease tends to be associated with an underlying adnexal or internal malignancy. There have been several reports of EMPD associated with carcinoma of the bladder, prostate, kidney, and colon. The association of hepatocellular carcinoma (HCC) with EMPD appears to be exceedingly rare; to our knowledge, it has been reported only once in the English literature. Herein, we report an unusual case of EMPD of the scrotum associated with HCC. EMPD was diagnosed 1 year after the appearance of an erythematous plaque, and HCC was noted 19 months after the diagnosis of EMPD. From our experience and literature review, in patients with nonspecific skin lesions that are unresponsive to conventional treatment, EMPD should be considered and skin biopsy performed. Long-term follow-up is needed to watch for the appearance of adnexal carcinoma or internal malignancy.

The case of a patient with surgically proven internal herniation of a loop of ileum through the sigmoid mesocolon is described. This 66-year-old man presented clinically with acute lower abdominal pain and an elevated white blood cell count. A computed tomography (CT) scan showed a thickened bowel loop with "bird-beak" appearance in the pelvis, centered towards the medial side and lying aside the effaced sigmoid colon. We think this CT picture is highly suggestive of internal herniation of the ileum through the sigmoid mesocolon, which is a rare clinical entity.

Lipoblastomatosis is a rare benign lipomatous tumour of childhood and infancy, classically showing high signal identical to fat on T1 weighted images. A case of histologically proven lipoblastomatosis in an infant is presented, in which MRI showed low signal on T1 weighted images identical to that of muscle instead of high signal. This appearance has not been previously reported.
