Summary: Pleomorphic adenoma of the lacrimal gland is a rare benign finding in adults, and extremely uncommon in children. These tumors often present with increased propotosis or hypoglobus, and they invariably require operative excision. While many of these lesions can be removed through a subcranial or transorbital exposure, larger and more posterior tumors occasionally necessitate an intracranial approach. This report describes a large lacrimal gland pleomorphic adenoma in a 16 year-old patient that required use of an expansive intracranial exposure to ensure complete excision including the capsule. We contrast this case and its management to other pediatric cases described in the literature.

Aggressive digital papillary adenocarcinoma is a rare eccrine sweat gland malignancy that is frequently misdiagnosed at initial presentation. Histologically, this tumor is similar in appearance to many adenocarcinomas and as such may be diagnosed as a metastatic lesion. We present the case of a patient with digital papillary adenocarcinoma, which was initially diagnosed as a felon. No consensus has been published regarding the treatment of this disease. A review of the diagnosis, pathology, treatment, and adjunctive treatments of aggressive digital papillary adenocarcinoma are also included.

Background: Methotrexate (MTX) is widely used as an immunosuppressant, chemotherapeutic, and abortifacient agent. It is also a potent teratogen, and intentional or unintentional exposure during pregnancy is associated with heterogeneous birth anomalies. Methods: We retrospectively reviewed a cohort of patients who presented to our clinic with limb anomalies in the setting of MTX embryopathy. Results: In our case series, we describe 7 cases of patients who had limb anomalies with heterogeneous functionality, from severely debilitating to completely asymptomatic. Most of the upper extremity anomalies in our group were managed conservatively. Conclusions: Methotrexate embryopathy is a rare but clinically important entity with phenotypic and functional variability. This series underscores the need for proper counseling of patients and raises concern regarding using this medication for the purpose of abortion.

Summary: Neonatal compartment syndrome is a rare condition characterized by progressive limb ischemia and tissue necrosis manifesting at birth or in the immediate postpartum period. Early recognition of clinical features and immediate surgical intervention offer the best prognosis, but unfamiliarity with this uncommon entity often results in delayed diagnosis and catastrophic consequences, including limb amputation. We present a case in a preterm neonate who developed a proximal arterial thrombus after sustaining limb ischemia in utero. This case demonstrated that even delayed treatment with appropriate therapy can result in salvage of the limb. Clinicians should be aware of the characteristic skin findings and institute appropriate measures to determine the presence or absence of compartment syndrome.

Harlequin ichthyosis (HI) is associated with high mortality. Early systemic retinoids are widely used, although their use remains debatable. We reported two neonates with homozygous mutations in ABCA12 consistent with harlequin ichthyosis who survived to discharge home with intensive care and without use of systemic retinoids.

Thermal ring injuries are rarely reported in the literature. For this reason, treatment is varied without a standard approach. We describe a case of a thermal wedding ring injury sustained during a welding accident. It is critical to understand the 3 zones of burn injuries when managing these infrequent cases. Furthermore, the dynamic progression that ensues a thermal burn will directly affect outcome. A case is presented along with a graduated approach to the management of such injuries.
