Light chain amyloidosis of the lacrimal glands in a patient with chronic dacryoadenitis
Amyloidosis is a heterogeneous collection of conditions that presents with variable organ dysfunction due to extracellular aggregation of abnormally folded proteins. Systemic light chain amyloidosis is an uncommon disease, and involvement of orbital structures is particularly rare. We present a case of chronic dacryoadenitis in which λ light chain amyloid deposition was detected in the lacrimal gland 6 months after a nonspecific biopsy.A rare case of invasive sino-orbital aspergillosis arising from isolated frontal sinus infection
Sino-orbital aspergillosis is an uncommon condition that occurs when infection of the paranasal sinuses extends into the orbit. Infection most frequently originates from the maxillary sinus, followed by the ethmoid and sphenoid sinuses. The frontal sinus is rarely involved, and is largely infected secondary to adjacent sinuses. Isolated aspergillosis of the frontal sinus is extremely uncommon, with approximately 30 cases reported in the literature.1–3 Here, we present a case of invasive sino-orbital aspergillosis arising from isolated frontal sinus infection in an immunocompromised patient.
