Abstract

Angina bullosa hemorrhagica (ABH) is a disorder of unclear aetiology characterized by abrupt and unprovoked presentation of blood-filled blister over the oral mucosa. Histopathology reveals sub epithelial blister containing erythrocytes with superficial perivascular lymphocytic infiltrate. We report two cases of ABH of which one was idiopathic and other was associated with chronic renal failure on hemodialysis.

 Introduction



Angina bullosa hemorrhagica (ABH) is a sub epithelial oral mucosal Hemorrhagic blister of unknown aetiology. This condition was first described in 1933 by Argentina [1] as traumatic oral haemophlyctenosis and Badham [2] in 1967 first used the currently accepted term ABH. Clinically, it presents as acute, spontaneous, asymptomatic hemorrhagic vesicle/bullae, commonly on the soft palate in middle aged individuals without any sex predilection. Histopathology reveals subepithelial blister containing RBC's with superficial perivascular lymphocytic infiltrate. Though exact aetiology is not known, many local and systemic factors are incriminated in the causation of ABH. We report two cases of ABH which was idiopathic in one case and other was associated with chronic renal failure on hemodialysis.

 Case Reports



Case 1

A 48-year-old woman presented with asymptomatic recurrent blood filled blister in the oral cavity with a history of irregular and intermittent appearance since 25 years. In most instances, lesion appeared singly on the lateral aspect of tongue but also involved soft palate occasionally. Each episode lasted for an average of three to four days. Lesions healed spontaneously without any sequel but lesion recurred every year once or twice without any seasonal predilection. No history of similar lesions elsewhere on the body. No history of intake of any other drugs, No history suggestive of precipitating factors like trauma, steroid inhalation, blood dyscrasias. Not a known diabetic, hypertensive or asthamatic. No significant family history.

On examination, there was solitary oval tense hemorrhagic bulla measuring about 2 × 1.5 cm over the lateral margin of tongue on the right side [Figure 1]. Surrounding mucosa was normal without any evidence of erythema or scarring. Lesion ruptured on manipulation with oozing of clear and thin blood mixed fluid.{Figure 1}

Case 2

A 50 years old male patient with chronic renal failure since two years, on haemodialysis since 8months with blood pressure, developed hemorrhagic blister at the junction of buccal mucosa and alveolar ridge on right side. Over a period of 12 hrs it ruptured discharging thin clear blood mixed fluid and healed within four days without any scarring or other squeal.

On examination, there was solitary oval tense hemorrhagic bulla measuring about 2.5 × 2 cm present at the junction of buccal mucosa and alveolar ridge on right side. On manipulation it ruptured easily [Figure 2].{Figure 2}

Tzanck smear in both cases showed numerous RBC's and there was no acantholytic or multi-nucleated giant cell. Biopsy from case -1 of the ruptured blister revealed sub-epithelial split with minimal perivascular infiltrate. Biopsy could not be done in case -2, since the patient did not consent. Routine blood and urine tests including Bleeding and clotting time, Liver function test, Renal function test, thyroid function test, lipid profile, Ultra sound examination of abdomen and pelvis, chest - X ray were within normal limits in Case-1. In case-2, all the investigations were normal except for high blood pressure (130/90 mm Hg) and elevated serum urea and creatinine levels (50 and 2.5 mg/dl respectively).

Spontaneous onset, isolated nature, constant presence of blood in the blister fluid and rapid healing in the absence of an identifiable local cause or systemic disorder differentiates ABH from mucous membrane pemphigoid, bullous pemphigoid, bullous lichen planus, epidermolysis bullosa, dermatitis herpetiformis, linear IgA disease and oral amyloidosis. The classical history and morphology of lesions helped us to arrive at the clinical diagnosis of angina bullosa hemorrhagica in both the presenting cases.

 Discussion



ABH is a benign phenomenon that is characterized by the sudden appearance of a blood filled blister on the oral mucosa in the absence of an identifiable cause or systemic disorder, commonly seen in middle and elderly people with no sex predilection. Bulla is typically seen on soft palate and occasionally on lateral border of tongue, gingiva and buccal mucosa. [3],[4],[5] Rarely other sites such as pharynx and oesophagus can be involved. [6] Onset is rapid and blistering starts over few minutes which breaks down in minutes to hours to form shallow ulcer and heals spontaneously over 3-10 days. [2],[3],[7] Lesions are typically asymptomatic but may be preceded by mild burning sensation. Recurrences can be seen at the same or different oral site in 30% of people.Local factors implicated are trauma from hot foods, dental procedures and endoscopy, local anaesthesia, and chronic steroid inhalation and systemic causes are hypertension, asthma, diabetes, rheumatoid arthritis, gastrointestinal disturbances and hyperuracemia. [3],[4],[5] Yamamoto et al. in his report of 11 cases, described a case of ABH associated with renal failure. [3] It has been known that ABH presents with recurrences at regular intervals, usually associated with some internal disease or with some medications. In our cases reported here, Case-1 had a classical presentation with pronged history of irregular presentation for 25 years without any other associated disease or drug intake. Case 2 presented with a classical presentation of first episode associated with Blood pressure and renal failure on dialysis. These cases are reported for the relative rarity of this entity and the diversity of presentation with reference to site within the oral cavity (In case -1, presenting at an atypical site) and diverse aetiology.This report though does not convey significant new information it would certainly help to create more awareness among dermatologists and oral physicians to be able to differentiate from a host of other blistering disorders of varying aetiologies in the oral cavity.
