Hypercalcemia from cosmetic injections can be severe and life threatening and can present years after the initial procedure. Cosmetic injection-associated granuloma should be considered a cause of hypercalcemia, especially in middle-aged females presenting with non-PTH-mediated, non-malignant hypercalcemia, which is often associated with elevated calcitriol; however, it should be noted that calcitriol level may be normal as well.

Statin-associated necrotizing myopathy is a symmetric proximal muscle weakness associated with extreme elevations of CK. It is common in males and can occur after months of statin use. It is associated with necrosis on muscle biopsy and the presence of anti-HMG-CoA reductase antibodies. It usually requires discontinuation and immune suppression for resolution. Rechallenge with statin is unsuccessful in most cases.

APS should be considered in young patients with AMI, especially if previous unprovoked thromboses, lower platelet counts, high partial thromboplastin times, and normal coronary arteries or coronary thromboses are identified.

Thyrotoxic periodic paralysis is a potentially life-threatening condition associated with recurrent episodes of muscle weakness and hypokalaemia due to hyperthyroidism. Diagnosis is often delayed or misdiagnosed due to its rarity in the western world and subtle features of hyperthyroidism on initial presentation. Here we present the case of a 25-year-old man who presented to the emergency department (ED) with sudden onset weakness of bilateral upper and lower extremities. His labs revealed hypokalaemia with elevated T4 and suppressed thyroid-stimulating hormone and he was diagnosed with thyrotoxic periodic paralysis. He was treated with potassium repletion, atenolol and methimazole with complete reversal of his paralysis within the next day. Unfortunately, he failed to keep the follow-up appointment after discharge, ran out of his methimazole and landed up in the ED again.

Thyroglossal duct cyst carcinoma is rare and occurs in just 1% of cases with thyroglossal duct cysts. It is not always possible to distinguish a thyroglossal cyst harboring malignancy from its benign counterparts unless biopsied, thus posing the dilemma. Currently there is no clear consensus on the optimal management of thyroglossal duct cyst carcinoma. Here we present the case of a 69-year-old female who presented with a midline neck mass and dysphagia and was found to have papillary thyroid cancer in the biopsy specimen of the neck mass. She underwent excision of the mass and the thyroglossal duct cyst along with total thyroidectomy; however, the thyroidectomy specimen showed no malignancy. Her lymph node mapping was negative and she is awaiting radioactive iodine treatment.

Apixaban is a direct oral anticoagulant that works by inhibiting factor Xa. It has been associated with adverse bleeding outcomes including atraumatic splenic rupture. We present the case of an 86-year-old man who presented with features of left upper abdominal pain and hemorrhagic shock found to have atraumatic splenic rupture and hemoperitoneum on imaging.
