Bilateral lacrimal system involvement by sclerosing extramedullary hematopoietic tumor

open access: yes, 2019
A 60-year-old man with myelofibrosis and extramedullary hematopoiesis was referred for evaluation of “swollen lacrimal glands.” Examination disclosed bilateral firm, immobile, nontender masses in the lacrimal sac fossa with no associated signs of ...

Evaluation and Management of Lacrimal Gland Diseases

open access: yes, 2020
The lacrimal gland is the epicenter of a broad spectrum of neoplastic and inflammatory diseases. Space-occupying lesions of the lacrimal gland and its fossa constitute approximately 5–13% of orbital masses upon biopsy.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Morphological and morphometric studies on the axial skeleton of the sitatunga (Tragelaphus spekii gratus)

open access: yesBMC Zoology, 2022
Background Anatomical features of the skeleton of wild animals contribute largely to their adaptation. A dearth of information on the skeletal anatomy of the sitatunga (Tragelaphus spekii gratus) necessitated this study.

Epithelial Tumors of the Lacrimal Gland

open access: yes, 2022
Space-occupying lesions of the lacrimal gland and its fossa constitute approximately 5–13% of orbital masses upon biopsy (Shields et al., Arch Ophthalmol 102:1606–1611, 1984; Reese, Trans Ophthalmol Soc UK 91:85–104, 1971; Kennedy, Trans Am Ophthalmol ...

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

open access: yesThe Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Distribution of Lacrimal Lacrimal Fossa in Cercopithecids.

open access: yesAnthropological Science, 1994
The skeletal composition of the lacrimal fossa, classifiable as a totally lacrimal lacrimal fossa (L-LF) or a maxillo-lacrimal lacrimal fossa (ML-LF), was observed in 1890 skulls of cercopithecids. The incidence of the L-LF is highly variable among cercopithecines, and is very low or non-existent in colobines as well as in hominoids.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...
