Purpose: Congenital dermal sinuses are a rare form of spinal dysraphism. The developmental defects are located along the midline neuroaxis, with sinuses in the cervical region being the least common. Congenital dermal sinuses can be associated with intraspinal infection as they act as a direct route from the skin and subcutaneous tissues into the spinal cord.
Methods: The authors present two cases of cervical dermal sinuses complicated by intramedullary abscess. Both children presented with neurological decline and febrile illness. MRI showed intraspinal abscess. Both underwent prompt surgical excision of the sinus tract, exploration of the cord and intravenous antibiotics.
Results: Both patients demonstrated excellent neurological recovery.
Conclusions: Complete surgical excision of the sinus and tract in addition to long-term antimicrobials can yield excellent neurological outcomes. At surgery, do not expect to find pus when exploring the intramedullary component. Long-term follow-up is advocated due to potential late recurrence.

Department of Dermatology, Institute of Child Health, Kolkata, India.
Introduction: Deep mycoses acquired by penetrating trauma to the skin can have varied and sometimes atypical morphological presentations resulting in diagnostic dilemmas and delay in treatment onset. Histopathology can be a useful tool in not only diagnosing but also differentiating various deep mycoses.
Aims And Objectives: To observe various morphological presentations and histopathological features of deep fungal infections.

Article Synopsis
- - A 10-month-old boy with a frontonasal encephalocele was found to have a mother with a nasal dermal sinus, marking a rare case of these two central nervous system malformations occurring in a parent-child relationship.
- - This is significant because similar cases have not been documented before, suggesting a possible hereditary connection between these types of malformations.
- - The case highlights the need for further research into the genetic factors behind these defects, which could help in predicting their occurrence within families in the future.
Intravascular papillary endothelial hyperplasia of the maxillary sinus extending into the contralateral nasal cavity.
Eur Arch Otorhinolaryngol

Department of Otorhinolaryngology, Faculty of Medicine, Juntendo University, 2-1-1 Hongo, Bunkyo-Ku, Tokyo, 113-8421, Japan.
Introduction: Intravascular papillary endothelial hyperplasia (IPEH) predominantly occurs in the subcutaneous and dermal regions and rarely originates from the sinonasal mucosa.
Case Presentation: We report on the case of a 58-year-old male patient who presented with progressive bilateral nasal obstruction, left-sided epiphora, and intermittent epistaxis. Computed tomography revealed a soft tissue opacity in the left maxillary sinus with intersinusoidal nasal wall demineralization, extending into the surrounding ethmoid cells and the right nasal cavity through a contralateral deviation of the nasal septum.
How to Reduce Inferomedial Orbital Wall Fracture Using a Navigation System: Tips and Pearls.

The orbit is a confined space with a defined bony structure. Bony protrusion into the ethmoid or maxillary sinuses by the blowout fracture can displace orbital tissues, including rectus muscles and adjacent fascial septae. Especially, reconstructing the orbit's floor and medial wall can be challenging when the inferomedial strut or posterior bony ledge is affected, leading to a loss of critical anatomic landmarks and support.
