Normal vessels are confined to the superficial lamina
propria, which prevents the shearing effects from the mucosa wave.
True sulcus vocalis results from scarring of the surface epithelium to the underlying vocal ligament as a result of loss or absence of the loose layer in between, known as the superficial lamina
However, studies with immunostaining and electrophysiological recordings have clearly established that peripheral nerve injury causes large myelinated fibres to begin to drive nociceptive neurons in superficial lamina
The superficial lamina
joined the deep surface of fascia iliaca as ribbon like bands.
The majority of celiac cases (27/36) demonstrated both surface epithelial staining with localization to enterocyte cytoplasm, superficial lamina
propria, and basement membrane.
The superficial lamina
spreads from a location caudal to the external acoustic meatus in all directions forming the temporal, occipital, cervical, and mandibular laminae.
A 45 year old female who underwent phacoemulsification for a cataract in the left eye, developed a partial split (the double ring sign) and eventual complete separation of the superficial lamina
of the lens capsule during capsulorhexis.
These tumors are poorly circumscribed, short fascicles of uniform spindle cells replacing the colonic lamina propria, especially the superficial lamina
propria, and separating and entrapping the crypts (Figure 3, A and B).
It consists of two laminae--a superficial lamina
derived from the ipsilateral latissimus dorsi and a deep lamina from the contralateral muscle (Bogduk and Macintosh 1984).
The current transurethral resection specimen showed a proliferation of numerous small tubular structures with attenuated hobnail cells, haphazard growth pattern, luminal blue mucin, and mild degenerative nuclear atypia, arranged in small groups and individually within the superficial lamina
propria and muscle fibers.
However, the lesion in our patient represented an area of scar with a loss of the superficial lamina
propria in a discrete area, leading to the adherence of the epithelium to the vocal ligament.
Histologic findings included patchy lamina propria inflammation composed of plasma cells, lymphocytes, and eosinophils (Figure 1), patchy surface epithelium lymphocytosis (Figure 2), and deposition of eosinophilic material resembling collagen within the superficial lamina
propria (Figure 3).
