The long-pulsed Nd:YAG laser in conjunction with topical steroids shows promising results in the treatment of AKN, particularly the papular component, and is well tolerated by patients.

Pheochromocytoma is a rare adrenal gland tumor that is often difficult for physicians to diagnose because of its general, nonspecific complaints. Diagnosis is particularly difficult in patients with neurofibromatosis 1, because pheochromocytoma in these patients will mimic other cardiovascular abnormalities. The authors report the case of a 60-year-old woman with an extensive history of hyperlipidemia, malignant hypertension, coronary artery disease, and neurofibromatosis 1 who was referred for an elective cardiac catheterization as a result of an abnormal stress test. The patient returned to the hospital 3 days after the procedure complaining of increased angina and palpitations. While hospitalized, she developed severe episodic hypertension. A computed tomographic scan revealed bilateral adrenal masses. Findings of biochemical and imaging evaluation confirmed the diagnosis of bilateral pheochromocytoma. Early screening of pheochromocytomas in high-risk populations is essential for prompt diagnosis and successful management.

<p>Interstitial granulomatous dermatitis is a rare dermatologic condition characterized by erythematous papules, nodules, and plaques, most commonly on the trunk and limbs. It is commonly associated with comorbidities such as arthritis, autoimmune disease, lymphoproliferative disorders, and malignancies. In addition, the rash can be medication-induced, which is differentiated by histopathologic results. Diagnosis is confirmed with skin biopsy, and treatment is individualized to each patient. Here we report an 89-year-old man with sudden onset lower extremity interstitial granulomatous dermatitis with the concurrent diagnosis of diffuse large B-cell lymphoma. Treatment of the skin lesions was attempted with a combination of steroids, antibiotics, antifungals, and disease-modifying anti-rheumatic drugs, without complete resolution.</p>
