Mass lesions of the head and neck in infants and children can be either developmental, inflammatory or neoplastic. Lymphomas (Hodgkin's or Non-Hodgkin's) commonly present as neck lumps in children. Although malignancy is not the commonest aetiology of paediatric cervical lumps, a high index of suspicion is critical to facilitate early diagnosis and treatment of cervical lesions. We present the case of a 15-year-old boy who presented with a solitary midline cervical lesion, which simulated a thyroglossal cyst on clinical examination. However, histopathological examination revealed it to be a Hodgkin's lymphoma. Related literature is also reviewed.

Lymphocytes are generally non-adherent. This makes it challenging to fabricate three-dimensional (3D) structures mimicking the three-dimensional lymphoma microenvironment in vivo. This study presents the fabrication of a hemispherical 3D lymphoma model using the on-chip Cell Dome system with a hemispherical cavity (1 mm in diameter and almost 300 µm in height).

The ocular tissue is one of the most densely populated tissues in the body with extremely small blood vessels, and vascular lesions have been reported to be a factor in vision loss and visual field defects in many ocular diseases. Currently, vascular endothelial growth factor (VEGF)-targeted agents are the first line of treatment for intraocular vascular lesions, however, there are some cases in which they are not fully effective. Therefore, we explored pathogenic molecules other than VEGF, aiming to develop new molecular-targeted therapy.

BACKGROUND Fibrosing mediastinitis (FM) is a rare, fibroproliferative disorder within the mediastinum. It is extremely rare for hematologic malignancies to develop as FM. CASE REPORT A 32-year-old Japanese man with a 1-month history of headache and 2-week history of facial swelling underwent chest computed tomography (CT); a diffuse mass-like lesion was revealed in the anterior mediastinum with severe stenosis of vital mediastinal organs.
