| An unusual auricular
malformation accompanied by accessory tragus: macrotragus.
Eur Arch Otorhinolaryngol. 2007 Oct 25;
Definition of malformations of
the tragus is important for terminology and treatment. Most common
entities are the skin tag, accessory tragus, preauricular sinus, and
cyst, whereas macrotragus is an uncommon and unaddressed deformity
that should be distinguished from these. In this report, three cases
with diagnosis of the macrotragus are presented. The tragus was
uniformly large and displaced anteriorly, and external auditory meatus
was not obliterated in all cases. For correction, excision of the
excess tragal cartilage and skin was performed. In all cases,
bilaterally symmetric tragus was achieved. There were no complications
in the early postoperative period and there was no enlargement after 6
months of observation. Macrotragus and accessory tragus are different
entities that should be distinguished for accurate diagnosis. They
have similar histopathological but distinct anatomical
characteristics. Although both are treated by a simple excision, in
the case of macrotragus, special effort should be taken to leave
enough cartilage to restore normal tragal contours.
Accessory tragus: A report of
2 cases.J

The purpose of this article
was to review the embryology of the external ear, as related to the
clinical finding of accessory tragus (ear tags). Medical management of
the accessory tragus is discussed, as well as differential diagnoses
and associated syndromes. A general clinical description of accessory
tragus is described, and 2 specific cases in pediatric patients are
presented.
Accessory tragus: report of
two cases and review of the literature.Pediatr
Dermatol. 2000 Sep-Oct;17(5):391-4.
Accessory tragus is a fairly
common congenital malformation of the external ear. In the vast
majority of cases it is an isolated developmental defect not
associated with other abnormalities. However, the remote possibility
exists that it could be associated with other abnormalities of the
first and second branchial arch. Accessory tragus is a consistent
feature of the oculoauriculovertebral syndrome (Goldenhar syndrome).
When correctly identified, surgical excision of accessory tragus is
quite simple and rarely results in any complications.

tragi: variable quantity of adipose tissue in connective tissue
framework. Pediatr
Dermatol. 1997;14(6):433-6
Controversy
exists about the histologic differences between hair follicle nevi and
accessory tragi. We examined 10 congenital lesions histologically,
possible diagnoses of which were hair follicle nevi or accessory tragi.
Two specimens out of the 10 had tiny, mature hair follicles surrounded
by thick fibrous root sheaths, a few fat cells, and no cartilage. The
subcutaneous fat cells of their bases were segmented by a connective
tissue framework. They had histologic features of hair follicle nevi.
One specimen had cartilage and abundant fat cells with a connective
tissue framework in the nodule, as well as a conglomeration of
numerous well-differentiated hair follicles. It possessed both
elements of a hair follicle nevus and an accessory tragus. Seven
specimens had abundant subcutaneous fat and showed a prominent
connective tissue framework. These were typical accessory tragi. The
present study suggests that the number of fat cells in the nodule or
papule differs between these two conditions. All the lesions studied
revealed a connective tissue framework in the subcutaneous fat.
Histologic features of both hair follicle nevi and accessory tragi can
coexist in a single lesion. Hair follicle nevi may represent
incomplete accessory tragi with scant fat cells.
Bilateral accessory
tragus. Cutis 1993 Mar;51(3):199-200.
Bilateral
accessory tragus is a rare congenital malformation of the external
ear. An isolated, nonfamilial occurrence of bilateral accessory tragus
in a forty-three-year-old man is presented, and the literature is
reviewed. Congenital firm, preauricular papules should be recognized
as accessory tragi.
Histological diagnostic criteria for
accessory tragi. J
Cutan Pathol. 1990 Aug;17(4):206-10.
The histological features of
accessory tragi from 13 patients were analyzed. All the lesions showed
numerous tiny mature hair follicles in various phases, while the
presence of cartilage was not essential. Of importance was the
prominent connective tissue framework in the subcutaneous fat that
seemed to be one of the diagnostic criteria for accessory tragi.
