  eMedicine - Rhombic Flaps : Article by Anthony P Sclafani, MD
The term rhomboid is frequently used in facial reconstruction literature to mean either rhombuslike or to describe one of the popular transposition flaps used to repair rhombus-shaped defects.
Rhomboid flaps rotate neighboring tissue to close the primary surgical defect, whereas the donor site is closed by primary closure.
All rhomboid flaps are closed under some degree of tension, and this tension is characteristically unevenly distributed along the flap's length.

In geometry, a rhomboid is a parallelogram in which adjacent sides are of unequal lengths and angles are oblique.
Euclid never uses the definition of rhomboid again and introduces the word parallelogram in Proposition 31 of Book I; "In parallelogrammic areas the opposite sides and angles are equal to one another, and the diameter bisects the areas." Heath suggests that rhomboid was an older term already in use.

Median rhomboid glossitis was thought to be a developmental anomaly caused by failure of the lateral lingual tubercles to cover the tuberculum impar.
Morphologic changes of experimentally induced candidiasis of the tongues of rats[5] are similar to the changes seen in median rhomboid glossitis, which further supports candidial infection as an etiological agent for the lesion.

 Rhomboid rows---good for everybody, esp. women
Really, you're just doing a chest fly, but you're doing it while lying face down, on your sternum, so the rhomboid muscles that support your shoulder blades from spine to shoulder blade are doing the lift to pull the dumb bells back to the fully extended position parallel to your chest.
The dumb bells are at rest when they meet in front of your sternum, and when you pull them away so that they are parallel with your pectorals, you are at the point of greatest stress.
The rhomboid rows will offset that pulling by creating a tightening rhomboid pull from the back.

 Genome Biology | Full text | The rhomboids: a near ubiquitous family of intramembrane serine proteases evolved via ...
Although the near universal presence of the rhomboid family in bacteria, archaea and eukaryotes appears to suggest that this protein is part of the heritage of the last universal common ancestor, phylogenetic tree analysis indicates bacterial origin with subsequent dissemination via horizontal gene transfer.
Rhomboids are missing in the microsporidium Encephalitozoon cuniculi, a eukaryotic intracellular parasite with a highly degraded genome, the archaea Methanothermobacter thermoautotrophicus and Thermoplasma volcanium, and several bacterial species, primarily parasites with small genomes but also species with moderate-size genomes, such as Xylella fastidiosum (see COG0705 at http://www.ncbi.nlm.nih.gov/COG/).
The phylogenetic tree of the rhomboid family tree shown in Figure 2 clearly follows neither the "standard model" scenario [22,23], with the major split between the archaeo-eukaryotic and bacterial lineages nor the "mitochondrial" scenario, which postulates acquisition of a gene by eukaryotes from the pro-mitochondrial endosymbiont.

 Picture of Median Rhomboid Glossitis   * Otolaryngology Houston
Median rhomboid glossitis is an enigmatic inflammatory or infectious condition of the dorsum of the tongue.
Median rhomboid glossitis is an uncommon condition; the estimated prevalence in adults is less than 1%,  The condition is usually asymptomatic or may cause a slight burning sensation associated with spicy foods.
The most common presentation of MRG is a red or red-white patch on the midline of the dorsum of the tongue, just anterior to the region of the V of the circumvallate papillae (sulcus terminalis).

The flap used was the rhomboid flap with skin and subcutaneous tissue and in 23 cases included breast tissue.
After marking the extension of the tumor, the rhomboid flap was designed without compromising the safety margins and with the pedicle turned to the breast.
The Rhomboid flap is a versatile flap to maintain the breast shape, avoiding a dorsal scar or mobilization of a muscle.

Rhomboids are a relatively recently-discovered class of serine proteases that have the unusual capacity to cleave substrates within their transmembrane domains.
There is growing evidence that rhomboids mediate key proteolytic processing activities during invasion by apicomplexan parasites (Zhou et al., 2004).
We are also actively investigating a family of putative rhomboid substrates on the merozoite surface.

 THE RHOMBOID RELEASE: A NEW APPROACH TO THE MANAGEMENT OF DIGITAL BURN CONTRACTURES
A new approach, the "rhomboid" release, was used for chronic moderate flexion contractures of the fingers due to burns in nine adult cases.
We used rhomboid release in 15 fingers of eight male and one female patients (aged 20-22 years), with moderate flexion deformities and extension deficits varying from 40 to 80' due to burns (Table 1).
We have found that rhomboid release, as named by us, is versatile and provides 5-8 mm of tissue gain in both the distal and the proximal edges of the contracture, making a total gain of 1-1.6 em.

 Sports Medicine Advisor 2006.4: Rhomboid Muscle Strain or Spasm
Your rhomboid muscles are in your upper back, connecting the inner edges of your shoulder blades to your spine.
A rhomboid muscle strain or spasm is usually caused by overuse of your shoulder and arm, especially during overhead activities like serving a tennis ball or reaching to put objects on a high shelf.
Rhomboid strains and spasms are best prevented by warming up properly and doing stretching exercises before activities such as tennis, rowing, or overhead movements.

 Matthew Freeman - Rhomboid Intro
All rhomboids have multiple TMDs (typically six or seven) and it is proposed that they work by forming the classical charge relaying catalytic triad (famous from serine proteases like chymotrypsin) between their TMDs.
Although we discovered rhomboid’s function as an activator of EGF receptor signalling in Drosophila, they exist throughout evolution – from bacteria and archaea to humans – so the majority of organisms which have rhomboids don’t have receptor tyrosine kinases, let alone EGF receptors.
Amazingly, the bacterium Providencia stuartii uses a rhomboid to release an intercellular signalling molecule – a mechanism apparently analagous to the activation of EGF ligands by Rhomboid in Drosophila – implying a common signalling mechanism between bacteria and metazoans.

In this current work, two Arabidopsis rhomboid protease homologs were cloned into an E. coli bacterial expression system in the presence of Tic40, an integral plastid envelope protein.
This in vitro assay presents a simple method of affirming the possibilty that Tic40 is a substrate of at least one of the plant rhomboid protease homologs.
It is hypothesized that the plant rhomboid protease functions in the processing of a Tic40 preprotein to its mature form for its correct localization to the inner membrane of the chloroplast envelope.

It's possible that rather than a rhomboid strain, you may have a trapezius strain.
In the case of either, there may be a cause from muscle overbalance/weakness that causes a slight misalignment in the vertebral column[subluxation], which will press a nerve and cause it to fire, resulting in muscle soreness or a spasm.
That knot you feel, and the swelling is your muscle[trapezius, rhomboids, etc] and tissue around it.

When the shoulders round forward it’s an indication the rhomboids are stretched, usually as a result of overworked pectoral muscles.
Because if that upper quarter slides forward, the entire weight of the shoulder girdle is moving down and forward in front of the body, creating excessive tension on all of the muscles on the back of the neck and the shoulder blades.
