Midfacial destruction is a rare presentation of various neoplastic, autoimmune and infective disorders. Here we present a rare case of a midfacial distructive lesion in a young patient with xerodermapigmentosum, which was diagnosed as acantholytic squamous cell carcinoma on histopathological examination.
Acantholytic squamous cell carcinoma (ASCC) first described by Lever in 1947 is a rare variant of squamous cell carcinoma (SCC) characterized by features of acantholysis of cell nests resulting in a pseudoglandular appearance [1,2]. (synonyms: adenoid SCC, angiosarcoma-like SCC, pseudovascular adenoid SCC, pseudoangiosarcomatouscarcinoma, adenoacanthoma) . It accounts for 3-4% of all squamous cell carcinoma types and most commonly seen in the sun exposed areas of skin particularly of elderly with a male preponderance [1,2]. Here we report a case of young female with XerodermaPigmentosum presenting as a destructive lesion of the midface which on further evaluation was found to be Acantholytic squamous cell carcinoma.
A 26 year old female presented to the ENT outpatient department with 8 days history of bleeding from the nose. She also had complains of continuous dull aching pain from a slow growing ulcer present on the right side of her face. It was associated with foul smelling discharge. The ulcer has been present since one year which started as a small swelling, later ulcerated and progressed to the present size (Figure 1). Clinical examination revealed an ulcerative lesion about 5x6 cms, irregular in shape with everted edges. Floor of the ulcer showed pale granulation tissue with maggots and blood clots. Foul smelling serosanguinous discharge was present. Surrounding skin showed hyperpigmented exfoliative lesions. Patient also had skin lesions all over her body which was present since her childhood.
On diagnostic nasal endoscopy a friable mass was seen filling the right nasal cavity extending to left side with septal involvement. It was sensitive to touch and bled on touch. Examination of the oral cavity revealed a 2x3 cms swelling present over the hard palate, tender, firm and with well defined margins. Multiple biopsies were taken from edges of ulcer, nasal component of the mass and palatal lesion and were sent for histopathological examination. There were no palpable neck nodes Patient was examined by a dermatologist and was diagnosed to have xerodermapigmentosum. Family history of similar skin lesions was present in her cousins. Biopsy from the suspicious lesions from patient’s forehead and back were also taken. All routine hematological and biochemical investigations were normal including HIV, HBsAg and VDRL. Chest film and USG abdomen were normal [4,5]. A contrast enhanced computed tomogram (CECT) showed an ill defined soft tissue density lesion involving the right maxillary sinus extending into the nasal cavity causing destruction of walls of maxillary sinuses,
perforation of hard palate with extension into the oral cavity and
also extending to the right orbit (Figure 2).
Patient was then started on intravenous broad spectrum
antibiotics as well as non steroidalanti inflammatory drugs.
Regular debridement of infected ulcer of the midface with
removal of maggots was done. On day 4 wound was free of maggots and granulating floor was seen (Figure 3). Patient had
marked improvement of pain and facial swelling. There were
no further episodes of bleeding from nose. Histopathological
examination of biopsy from ulcer edges, nasal mass and palatal
swelling revealed final hisopathological diagnosis of rare variant
of squamous cell carcinoma known as acantholytic squamous
cell carcinoma (Figures 4 & 5). Histopathological examination
of second biopsy specimen taken from other skin lesions over
forehead and back showed features of basal cell carcinoma.
Patient was advised radical surgery and reconstruction for her
midface lesion. Patient refused for any curative treatment and
was referred for palliative treatment.
For any progressive destructive lesion of the midface
involving the nose, paranasal sinuses and oral cavity the
first provisional diagnosis that comes to our mind is Lethal
Midline Granuloma. However in this case the patient had
features of XerodermaPigmentosum (XP) because all the three
characteristic features of XP namely freckles, photosensitivity
and photophobia were present .This existing skin condition
widens our provisional diagnosis since these skin lesions can
predispose to a variety of skin cancers including basal cell
carcinoma(BCC), squamous cell carcinoma (SCC) and even
Malignant melanoma. Our first differential diagnosis was BCC as
it happens to be the most common skin cancer in patients with
XP. Other supporting factors were the site of the ulcer as well as
the history of progression, which started as a nodule and later
got ulcerated and developed to the present condition. Second
condition that had to be ruled out was SCC, the next common
malignant condition of the skin . The everted edge and history
also favored a squamous variant. Occasionally we even come
across patients whose mid facial lesions cannot be classified in
any particular group despite all investigations .Such patients are
described as suffering from an entity called “idiopathic midline
Acantholytic squamous cell carcinoma is a tumor which was
initially considered to arise from the sweat glands  due to its
tubular and gland like structures was later found to be a distinct
variant of SCC. There are very few cases of ASCC documented
so far and no specific risk factors have yet been identified.
Some proposed predisposing factors include previous scars,
burns, human papilloma virus infections, UV radiation and even
immuno suppression. The earlier thought of acantholytic actinic
keratosis as a precursor lesion is abandoned now since no exact
association was found . A documented case of ASCC originating
in patients with chronic lymphocytic leukemia is also present. It
is most often found on the head and neck region of elderly, but
other sites of origin also have been reported including the vulva,
penis, nasopharynx, and breast [7-13]. Intraoral ASCC should
be differentiated from angiosarcoma due to its histopathologic
similarity with the later.
While epitheliodangiosarcoma shows positivity for
endothelial markers, ASCC stains positive for only epithelial
membrane antigen (EMA) and cytokeratins . Overall the
mortality of ASCC compared to SCC is higher, the high mortality
rates mainly due to refusal of treatment or a reporting bias. The
suggested treatment protocol is wide excision of the lesion with
a safe margin with prophylactic neck dissection, followed by
adjuvant radiotherapy with chemotherapy wherever needed.
